If you’re reading this article, which is only available through the Internet, then you’re basking in a tsunami of electromagnetic radiation. Don’t worry though, the vast majority of these waves are so low power that they don’t make it through the first layer of your skin before dissipating harmlessly. Still they do carry power, enough so that this article can worm its way from the server all the way to the device that you’re reading it on. Considering just how pervasive wireless signals are in our modern lives it then follows that there’s a potential source of energy there, one that’s essentially free and nigh on omnipresent. Whilst this is true, to some extent, actually harvesting a useful amount of it is a best impractical but that hasn’t stopped people from trying.
If you’re a longtime fan of Mythbusters like myself you’ll likely remember the episode they did on Free Energy back in 2004. In that episode they tested a myriad of devices to generate electricity, one of them being a radio wave extractor that managed to power half of a wristwatch. In an unaired segment they even rigged up a large coil of wire and placed it next to a high voltage power line and were able to generate a whopping 8mV. The result of all this testing was to show that, whilst there is some power available for harvesting, it’s not a usable quantity by any stretch of the imagination.
So you can imagine my surprise when a product like iFind makes claims like “battery free” and “never needs recharging” based around the concept of harvesting energy from the air.
The fundamental functionality of the iFind isn’t anything new, it’s just yet another Bluetooth tag system so you don’t lose whatever you attach the tag to. It’s claim to fame, and one that’s earned it a rather ridiculous half a million dollars, is that it doesn’t have a battery (which it does, unless you want to get into a semantic argument about what “battery” actually means) and that it charges off the electromagnetic waves around you. They’ve even gone as far to provide some technical documentation that shows the power generated from various signals. Suffice to say I think their idea is unworkable at best and, at worst, outright fraud.
The graphs they show in this comment would seem to indicate that it’s capable of charging even under very weak signal conditions, all the way down to -6dBm. That sounds great in principle until you take in account what a typical charging scenario for a device like this would be, like the “ideal” one that they talk about in some of their literature: a strong wifi signal. The graph shown above is the signal strength of my home wifi connection (an ASUS RT-N66U for reference) with the peak readings being from when I had my phone right next to the antennas. That gives a peak power output of some -22dBM, which sounds fine right? Well since those power ratings are logarithmic in nature the amount of power output is about 200 times weaker which puts the actual charge time at about 1000 days. If you had a focused RF source you could probably provide it with enough power to charge quickly but I doubt anyone has them in their house.
There’s also the issue of what kind of power source they have as the size precludes it from being anything hefty and they’re just referring to it as a “power bank”. Non-rechargeable batteries that fit within that form factor are usually on the order of a couple hundred milliamps with rechargeable variants having a much smaller capacity. Similar devices like Tile, which includes a non-rechargeable non-replaceable battery, lasts about a year before it dies which suggests a minimum power drain of at least a couple mAh per day. Considering iFind is smaller and rechargeable I wouldn’t expect it to last more than a couple weeks before giving it up, Of course since there’s no specifications on either of them it’s hard to judge but the laws of physics don’t differ between products.
However I will stop short of calling iFind a scam, more I think it’s a completely misguided exercise that will never deliver on its promises. They’ve probably designed something that does work under their lab circumstances but the performance will just not hold up in the real world. There’s a lot of questions that have been asked of them that are still unanswered which would go a long way to assuring people that what they’re making isn’t vaporware. Until they’re forthcoming with more information however I’d steer clear of giving them your money as it’s highly unlikely that the final product will perform as advertised.
I can think of a few titles where bugs or glitches were not only expected they were also thought of being one of the many sources of enjoyment of the game. The Elder Scrolls series is a prime example of this as their titles are almost always riddled with numerous bugs on release and Bethesda’s stance of not fixing the fun (but not game breaking) shows that many players get an awful lot of enjoyment out of their game behaing unexpectedly. I had yet to see a game where bugs, glitches and weird physics were actually the game itself until I came across Goat Simulator, a title from indie game developer Coffee Stain Studios. Whilst it’s definitely an unique concept there’s a limit to how much whacky physics fun you can have before you start to tire of it.
You’re a goat (surprise surprise) and the game centers around you being a goat in a section of a small town. Strictly speaking there are no objectives, there’s no over-arching plot to drive you forward nor any motivation provided for you being where you are, and so you’re free to roam the world doing as you wish. In traditional Goat spirit this of course means destroying anything and everything in your path, headbutting anything that might get in your way. Once you tire of that though there are many hidden challenges for you to unlock, some of which provide you access to powers beyond your wildest goaty dreams.
For a game that was slapped together in the space of a couple months Goat Simulator has a level of graphical fidelity that I honestly didn’t expect. It uses the Unreal 3 engine so you wouldn’t expect graphical miracles from it but the incorporation of atmospheric effects and modern lighting has Goat Simulator punching well above its weight class in terms of graphics. It still runs perfectly fine most of the time too (until you’re intentionally trying to break it, of course) something which, again, I wasn’t expecting. In all honesty for a game that was being touted as a bug ridden, hastily slapped together prototype there’s an incredible amount of polish. Much more than I’d come to expect from other developers of similar calibre.
Goat Simulator revolves around you being a goat that causes all sorts of carnage around the small suburban area that you find yourself in. In the beginning this will be pretty vanilla kind of stuff, destroying fences, headbutting people and generally running amok in the various areas available to you. This is all scored though so whilst your initial inclination will be to just ram things at random eventually you’ll try to figure out how to maximise your score. That’s when you’ll start to add a little strategy into your carnage, looking for places with a cornucopia of objects that you can goat your way through. Of course along the way you’ll run into the hastily slapped together physics that provides much of Goat Simulator’s entertainment.
I started out by just following the prompts to try out different things which serves as a solid, light touch tutorial that doesn’t get in the way if you just want to rampage through the town. This introduces you to how the scoring mechanics work which are pretty similar to what I remember Tony Hawk Pro Skating being like when I last played it almost a decade ago. So whilst you can headbutt that box 100 times in a row your score probably won’t go up by much as the game wants you to try a variety of different whacky things. This helps to add a little direction to a game that would otherwise have been thoroughly confusing without trying to impose on those who couldn’t care less about it.
After a while though there’s really only 2 things that will keep you playing: score and achievements. For the most part getting the highest score is just a matter of patience and not breaking the game too hard (as that can lead to you needing to restart it or the game crashing). something which can only take you so far. The achievements provide some fresh perspective on the game by giving you access to “powers” which can be anything from dropping dead goats from the sky to an impossible to control jetpack. If you’re like me though once you’ve done most of these the rest of the achievements don’t really seem that appealing and all you’re left with is a haphazard physics simulator.
Which, I have to say, is an awful lot less buggy than I thought it would be. You can make the physics engine do some crazy things but they’re really nothing above what I’ve seen in other games that were supposedly coded with good physics engines. You can get people stuck in the wall and launch yourself into the stratosphere but other than that there’s really not much else to speak of. Even when I was deliberately trying to make the game crash (by spawning dozens of other goats and using the console to fiddle with engine settings) all I could accomplish was making the physics engine and game slow to crawl. So if you were expecting a game that was absolutely riddled with bugs you might be disappointed as it’s really anything but.
Goat Simulator is a fun distraction that showcases the enjoyment that gamers can get from emergent game play. Whilst it’s far from the bug laden, glitch filled adventure that many touted it as the core game mechanics are still fun with the added benefit of a whacky physics engine just adding to the mix. It’s a short lived adventure however as whilst it’s fun to rack up a high score there’s nothing really to keep you interested once the achievements are gone and you’ve played with all the powers. If the idea piqued your interest then I definitely recommend grabbing it but otherwise you’re not really missing out on anything if you decide not to play it.
Goat Simulator is available on PC right now for $9.99. Total play time was 2 hours with 62% of the achievements unlocked.
The quest to understand our origins is an innate part of our psyche as humans. You can see evidence of this stretching as far back as we kept records as our ancestors grappled with the idea of where they originated from, whether it was a (relatively) simple question of lineage or the larger question of where we, and all that we know of, came from. Modern science has made incredible leaps in this area, expanding our understanding to show that we live in a universe that is old beyond any of our wildest guesses and is home to more wonders than any could have dreamed of. Still the ultimate question, of where everything began, still puzzles us although as of today we’ve begun to lay down the first few pieces in this puzzle and they’re magnificent.
You’re likely familiar with the concept of the Big Bang, the theorized event that gave birth to our universe and marked the beginning of time. However the specifics of what happened during that time are the subject of intense debate among the scientific community and there are many theories that model what may have happened. One of the most popular theories is that during the Big Bang the universe underwent a period of massive inflation in the tiny fractions of a second after it began, expanding faster than the speed of light. There was a lot of indirect evidence to support this (like the fact that our universe is still expanding) but direct proof of this occurring had been elusive.
That was until the telescope picture above, called BICEP-2, caught a picture of something that could only exist if that theory was correct.
Our universe still has remnants of the Big Bang hanging around in something called the Cosmic Microwave Background (CMB). It’s a kind of radiation that’s pretty much uniform not matter which direction you look into, something which is pretty peculiar when you consider just how wide and varied everything else we can observe is. BICEP-2 was searching for something in particular though, a pattern in this radiation that could only have happened should the early universe undergone a period of rapid inflation. The technical term for this is primordial B-mode polarization and was widely believed to have a value of below 0.11 based on previous maps of the CMB. BICEP-2 on the other hand has come in at a 5 sigma confidence level (1 in 3.5 million chance of being random, the gold standard for confirmation in this field of physics) as 0.2, excluding many models and theories that were based on that assumption. It opens up a whole new world of physics and is the first direct proof of the inflationary model.
To understand just how huge of an impact this is going to have on the world of physics you just have to see the reaction of Andrei Linde, one of the first to propose such a model, and his wife Renata Kallosh (also a well renowned theoretical physicist) reacting to the news:
It’s one thing to find proof of something and it’s another thing entirely to show something can not be. This discovery is powerful not because it shows us that a certain model is correct more it has shown us that the widely held belief was in fact wrong and we need to start heading in another direction. Confirmation of this shouldn’t be far off (indeed the team behind the discovery held onto the results for a year to make sure) and with that we’ll enter into a new world scientific debate, one that was so much more informed than before.
I’m sure everyone has heard of the idea of an unstoppable force meeting an immovable object. For anyone who’s interested in scientific principles it can be a pretty irritating thought experiment as you wrangle with definitions, principles and the limitations of your own knowledge of science. Personally I never really thought about it much past the point of thinking that they’d both be converted to pure energy (this makes the assumption they’re both physical objects with mass) but as it turns out there’s a much, much better explanation. One that makes me feel a little dumb for not researching it a little further:
The idea itself is in fact a paradox since the existence of one or the other of the two parts of the equation means that the other simply can not exist. If you have something that is immovable then its impossible for an unstoppable force to exist and vice versa. Indeed diving into the semantics of it like the video does makes their existence even more problematic, even if we ignore the energy requirements and just go by the laws of physics. I have to say that the end result of them simply passing through each other was not something that I would have expected but then again I only did 6 months worth of physics at university.
It sounds ludicrous right? Being able to travel faster than the wind using only the wind sounds like an incredibly crazy idea as for it to work there has to be some kind of other external force acting on it for that to work. Indeed the idea perplexed me for quite a while, in a much similar way as the airplane on a treadmill problem did, but once you get your head around the idea of apparent wind it starts to get a bit easier. Of course nothing beats a good example and it just so happens that there’s been a cracker of one to cross my decks recently.
The video above shows an intriguing vehicle called Sailrocket 2, a sail boat that has a rather intriguing design that allows it to travel at almost 3 times the current speed of the wind its in. The simplest way to explain this is that, as the design kind of suggests, it’s not travelling directly down the wind. It’s in fact travelling across the wind which causes it to experience another apparent wind due to the direction its travelling in which allows it to gain speed. Although this sounds a bit perpetual-motiony things like the hull resistance, efficiency of the sail and how close the boat can sail to the apparent wind it generates. Done right however you can get up to 6 times the speed of the prevailing winds which can be pretty damn fast as Sailrocket 2 demonstrates.
But what if I told you that, through some engineering trickery, similar things can happen travelling directly down the wind?
That my friends is a vehicle that is capable of just such a feat. The concept had been making waves for quite some time as whilst the idea of going faster than the wind whilst travelling across it is well known and proven doing the same thing travelling with the wind was seen as impossible. 2 years ago however a team headed by Rick Cavallaro built one of them and proceeded to set records with it not long after. It works by actually being two cars in one with its first mode of operation being directly driven by the wind and the second using the wind as a power source to drive the wheels directly (at least that’s my understanding anyway). This is what allows it to travel faster than the wind that’s driving it and makes for a pretty neat piece of engineering.
It’s this kind of non-intuitive science and engineering that really gets me going. I spent hours trying to understand all the principles behind this when I first heard of them and even now I’m still not 100% on them. That’s part of the fun though as the more I read about it the more I understand and the more interesting projects based on those ideas I uncover. It’s a rather deep rabbit hole to fall into however and I wouldn’t recommend it unless you’re as fascinated with science as I am.
Keen readers have noticed that my last couple months worth of game reviews are following a trend. Quite a lot of the titles are from independent developers and the vast majority of them have been shorter, simpler titles who’s play time doesn’t exceed more than 4 hours. I’ll be honest and say that the reason behind this is mostly because I’ve been thoroughly enjoying countless hours in DOTA 2 but it’s also because we’re in that lull that happens in the middle of the year where AAA titles have already been released or are due to be released soon. For me this lull used to be filled with MMORPGs and replaying old titles but the indie scene doesn’t care as much about marketing cycles as their publisher backed brethren do and that means I’m usually flooded with all sorts of interesting titles to have a crack at. Unmechanical is one such title that just happened to cross my path late Friday evening and based purely off the fact that it reminded me of Machinarium I felt it was worth a look in.
You play as small, propeller headed robot just casually going about your business with what I assume is your family of other propeller headed robots. Out of nowhere a pipe, very reminiscent of the ones in the Mario Brothers series of games, abducts you away from your family who seem to be blissfully unaware that this is going on. You then wake up in a cave deep underground which you then spend the entire game attempting to get out of.
Unmechanical is quite visually pleasing thanks in part to its development on the Unreal Developer’s Kit which it will constantly mention during the non-game events. It felt very reminiscent of Trine in that regard even though Trine uses its own in house engine but the visual styles seemed very comparable. The graphics aren’t exactly cutting edge and they have most definitely been heavily optimized for the 2D game play but the heavy use of stylization, modern lighting effects and vibrant colour palette mean that Unmechanical is always a pleasure to look at.
Physics based puzzle solving is the core game mechanic of Unmechanical. There’s nothing particularly unique about this particular mechanic, nearly every game with a physics engine these days incorporates some kind of puzzle solving element in it, but that doesn’t make it any less enjoyable. For the most part you’ll be picking up objects, moving them around and even doing a couple timed events that require precision placement in order to get everything working just right. In terms of the actual mechanics its pretty seamless as I never had any of the puzzles break on me but I did feel like there was a more subtle issue that could cause some people to get frustrated with Unmechanical.
Unmechanical is an incredibly simple game and this is by design. There’s no dialogue to speak of nor is there much in the way of explanation given for many of the things happening on the screen. This is fine however it also means that the way that most things work in this world are based around typical gaming conventions. Now depending on what kind of gamer you are some of these will be obvious and some will not. For me many of the puzzles made sense the second I saw them however there were a few where I had no idea what Unmechanical wanted me to do, leaving me to move wildly around trying to move everything in sight to see what would work. This could very well be part of the challenge but its one of those design choices that could very well lead to people dropping the game long before finishing it. I guess its not a fault per se, more something you need to be aware of going into it.
What really got me about Unmechanical though was just how good it was at telling a story without a whiff of dialogue. The screenshots don’t really do it justice and I won’t go into details about the actual story itself but suffice to say that there are enough visual clues to lead you to draw your own conclusions about the situation the main character is in, the world that surrounds it and ultimately the decision you make about how your journey ends. In essence the story can be as intricate and complex as you like or you can ignore it completely and just enjoy the puzzles. Both of these play styles would be rewarding in my view.
Unmechanical then was one of those pleasant surprises that I get every so often when I take a risk on buying a game that I know almost nothing about. The game mechanics might have been decidedly simplistic but the visual style and storytelling captivated me, enough so that I can’t bring myself to write it off as just another physics based puzzler with decent graphics. The heavy reliance on gaming conventions might make it something of a chore for some but for those who’ve got a few years of gaming experience under their belts I can’t see you struggling that much and indeed I believe there will be something in Unmechanical for nearly all gamers to enjoy.
Unmechanical is available on PC right now for $9.99. Game was completed in approximately 2.3 hours with 40% of the achievements unlocked.
This video is awesome not just because they built a water slide that lets you do a loop the loop but because it’s a very simple demonstration of the centripetal forces that are in play. You’ll notice that there’s quite a bit of lead up to the actual loop itself, a requirement so that when you start to loop up the sum of the forces ensures that you can overcome the effects of gravity. Too little and you’d only find yourself getting part way around the loop before tumbling down. Too much and you’d risk breaking the supporting structure but you’d have to be going at quite a clip to accomplish that.
If you want to see a good demo of the forces in action the Physics Classroom has a good post on it.
When I started out with this idea of doing 1 review a week it was mostly because I always seemed to find myself with a backlog of big name titles to play through. There aren’t however enough titles like that to sustain that kind of pace throughout the year and for the first 3 months of this year most of the titles I was reviewing were actually things released last year that I hadn’t got around to playing. Consequently I’ve found myself playing a lot of games that I wouldn’t have otherwise given a second thought to and Warp, the action-puzzle-stealth hybrid from Trapdoor, is one of those titles that I wouldn’t have considered playing.
Warp has you playing as an oddly shaped alien who’s named Zero (something I don’t think was made clear in the game, I certainly can’t remember anyone saying his name) waking up in an undersea laboratory. You’re surrounded by scientists who begin to perform surgery on you to remove a disk shaped object from you which turns out to be your internal power source. After a short obstacle course, which serves as the tutorial for the basics of the game, you are then reunited with your power supply and regain your ability to teleport short distances. Warp flows on from there, following Zero’s quest to escape the confines of the laboratory.
On first appearances Warp isn’t too much to look at, mostly due to its roots as a Xbox Arcade game. For the actual game play the graphics are fine with Warp making heavy use of lighting effects to cover up their less-than-stellar models but the cut scenes unfortunately didn’t appear to get any extra treatment to make them any better. Thus the artwork, graphics and sound work are all around the level I had come to expect from say around 5 years ago when I had friends tinkering with 3D models. Sure I can understand that there are limitations thanks to the target platform but when you don’t even bother to try and do rudimentary lip syncing for dialog scenes I get the feeling that a lot of this was done due to budgetary constraints rather than a lack of technical ability.
The core game play of Warp revolves around Zero’s ability to teleport short distances and also hide inside objects and people. At first it starts off with rudimentary things like finding non-obvious was to get around your environment but as the game progresses the challenges start to scale up dramatically. Zero also gains additional abilities as you complete levels augmenting himself with things like producing a controllable decoy (so you can get guards to kill each other), using said decoy to swap places with other objects and being able to launch objects a great distance. The combination of all these abilities makes for some rather interesting puzzles, some that are actually quite challenging to figure out.
Also thanks to the integration of a half decent physics engine there’s actually the opportunity for a lot of emergent game play which makes it a whole lot more interesting than your rudimentary puzzle game. Since every object can be moved and flung around quite easily there’s a lot of opportunity to break the intended solution by bringing objects along with you that the game doesn’t expect you to. There are also times when it goes horribly wrong like the travelator towards the end that you can change the direction of, try destroying both power supplies. The animation stops but you’ll still move if you stand on it. Still problems with the physics based game play are thankfully few, although Warp is far from free of issues.
Scattered throughout the game are challenges like the one above that push your use of certain skills to the limit in order to get extra “grubs” that are used to upgrade your abilities. These are usually timed affairs and in the words of someone I can’t remember “You know how to make something not fun in a game? Slap a timer on it.” and that’s exactly how all these challenges feel: not fun. I probably spent about a fifth of my in game time trying to get better than bronze on these challenges and I managed to get a few of them but at no time did I have fun doing it. It was kind of like Super Meat Boy all over again where the replay value is derived from it’s rather frustratingly hard difficulty. Not all of them were like this but the initial ones definitely were and it’s likely that it’s me being retarded, but there is another reason why I think its not.
The game is a very obvious port from Xbox360 to PC and that brings with it all the issues that are usually associated with them. For starters whilst the mouse is available in the initial start up screens it doesn’t work in the actual game for anything, not even the upgrade menus. Instead of redesigning the control paradigm around the mouse and the keyboard all the interface controls are simply remapped to the keyboard. This means that sometimes the game engine expects input in a certain way and doesn’t get it which can lead to all sorts of unintentional behavior. It’s not game breaking once you get used to it but it does smack of lazy porting just to grab another market.
The upgrade system is interesting at first glance, being able to augment your abilities in ways that change the game play significantly. As you can see above I chose to invest my grubs in certain keys skills, namely the ones that form the basis of the core game play (teleporting and moving faster). These definitely made the game somewhat easier as there were many times I could fudge my way through or get out of a situation that I wouldn’t have been able to do otherwise but looking over the other skills I couldn’t be sure why anyone would get them or how’d they make the game easier.
In fact I played the majority of the game sans these two skill upgrades mostly because I didn’t bother with the challenges nor religiously tracking down grubs in order to get said upgrades. This isn’t a problem with Warp per se, more the with the idea of combining a puzzle game with an upgrade system. For all the main challenges you’re going to have to give the player the required skills anyway and all the upgrades then can really only be making the player’s life easier. Deus Ex: Human Revolution did the upgrades that unlock other potential pathways/secrets bit quite well but they still had to accommodate for the possibility that the player didn’t choose a specific upgrade, at least for story critical sections. All of Warps sections appear to be story critical though, rendering the upgrade system kind of moot.
All that being said however I still found Warp extremely fun to play. I’m not sure how I’d describe it but the combination of puzzle solving, the over the top reactions from NPCs when they spotted you and the decidedly dark enjoyment you get from making people explode from the inside out made my time with Warp very enjoyable. This is in spite of the story that’s so thin on the ground that it might as well not even exist in the first place, something which indie games like this don’t usually forgo. Considering this game can be had for $20 as part of a 5 pack of games I think it’s incredibly great value for the time I spent with it and would recommend giving it a shot.
Warp is available on PC, PS3 and Xbox360 right now for $9.99 or equivalent on all platforms. Game was played entirely on the PC with around 5 hours of total play time and about 2/3rds of the grubs found.
I was a real late comer to the Trine party, only getting around to playing it early last year after it had been out for almost 2 years prior. Looking back over the review I wonder how much my opinion of the game would have changed had I played it soon after its release as for its time it would have really been quite a stand out title. In 2011, with the indie revolution in full effect, it’s unique take on the platformer genre was probably lost among other titles like Super Meat Boy. Still the game stuck with me and whilst I might be somewhat late to the party again I decided to venture back into the Trine world yet again.
Trine 2 puts you back in familiar territory, starting off with the wizard Amadeus being awoken from his slumber by an unearthly glow coming from his windows. Rushing out to investigate he finds that the glow was coming from the Trine itself, the magical artifact that had bound him in the previous games to Pontius the Knight and Zoya the Thief. Upon reaching the Trine Pontius appears from within the artifact and informs Amadeus that they have to once again save the kingdom from an as of yet unknown threat.
Everything about the look and feel of Trine 2 feels so much more ambitious than its predecessor. Whilst you could chalk much of this up to the 2 and a bit years between releases it still feels like a lot more effort went into the art direction, cinematography and art work. There’s heavy use of advanced lighting effects, depth of field and extensive camera work that I don’t remember being present in the original. The original Trine was colourful and vibrant and Trine 2 builds on that base to create something that, whilst possibly being a bit too colorful in some points (making it hard to determine what’s what on occasion), is a definite step up.
The core physics based platformer/puzzle solving game play remains true to the core of the original Trine whilst streamlining some aspects and adding in new types of puzzles that makes the sequel quite distinct. The wizard still conjures up objects, the thief can still grappling hook onto things and the warrior is still used purely for combat and has little to do with puzzle solving unless it involves smashing through a wall (although even that is made redundant by certain talent choices). The changes are for the most part positive with only a few minor issues that I feel need to be raised.
Both Trine and Trine 2 have the same shared experience leveling system but Trine 2’s deviates from the original’s significantly. Instead of getting 1 point to spend in each character’s talent tree you’re instead given 1 point per level to spend on any one of the 3 talent trees. The difference is quite stark as whilst in the previous game the puzzles could be designed around knowing what kind of abilities a player might have in Trine 2 you can pretty much short circuit most challenges by going a specific build. To be upfront about it you can pretty much make the game easy mode by dumping all your points into the wizard, letting you do things like this:
Now I have no idea how the developers intended to have that puzzle solved but I have the feeling it wasn’t supposed to be anything like what you’re seeing above. That’s part of the charm of the physics based game play, letting you create solutions that weren’t exactly intended, but when most of the puzzles were trivialized by a power leveled wizard it made me wonder why there weren’t some limits in order to stop you from doing this. I guess Frozenbyte thought that was part of the fun and I can’t say I disagree with them on this.
The combat of Trine 2 is pretty much identical to that of its predecessor; being a fun distraction from the core puzzle based platforming but not a whole lot more than that. For the most part it’s very hack ‘n’ slashy with you being able to spam your way through hordes of enemies even without the aid of additional talent tree upgrades. The boss fights start off interesting although they’re also prone to being beatable through mouse and keyboard spam. The final boss fight was actually pretty intense even if it felt like it was designed with only one of the 3 characters in mind. Overall I’d rate combat as passable, being more of a distraction than a core piece of the game play.
There are some notable bugs with combat however. Some enemies are easily confused by standing near or on top of them and not in an intentional this-is-part-of-the-game way. The type that I most often found this worked with was the dual fire blade wielding goblins who if you got close enough to then jumped behind would think you were still right in front of them. They’d then get stuck in a loop of attacking in that direction, allowing you to wail on them from behind with no consequence. Some of the boss fights bugged out in a similar way to a lesser extent but it was obvious that the enemies were coded with a rather simplistic AI. It’s a relatively small complaint in the grand scheme of things but it was definitely noticeable.
As a I alluded to earlier the talent tree has also been greatly simplified allowing you to level each character as you see fit. The choice of power leveling the wizard was a simple one, the more I leveled him earlier the more experience I got access to, leveling the others faster. As you can see from the screen cap above, taken about an hour before the end, I had nearly all the abilities. In the end I think there was only 2 I didn’t manage to get but even that doesn’t really matter considering that there’s a respec button at the bottom, one that can be used as often as you want with no consequences.
Additionally All the ancillary aspects of Trine 2 have been stream lined from the original. The mana bars for every character are gone completely which I thought was weird to begin with but after playing through the entire game without it I’m glad they took it out. All the mana bar did was add tedium to the game, forcing you to go back to check points in order to restock if you accidentally created the wrong object (which was far too easy in the original) or lost it all from spamming flame arrows.
The story of Trine 2 is somewhat thin on the ground, at least in comparison to recent releases, but it is serviceable enough to keep the game driving forward. Although there’s not a whole lot of dialog in the game the voice acting is above the level of what I’ve come to expect from games like these, with each of the character’s voices fitting well with their perceived personas. Just like the original Trine I’ll have to commend Frozenbyte for not taking the cheap option and leaving the ending open for yet another sequel, something that never fails to annoy me.
Trine 2 is a definite improvement over its predecessor in almost all respects. The visuals and art direction are a lot better, a definite sign that Frozenbyte has confidence in the IP and is willing to invest more heavily in it. The streamlined game play takes away the tedium making the game much more enjoyable overall. Overall I was quite impressed with Trine 2 not feeling the compulsion to play through to the end just for the review like I did with the previous one. Even if you haven’t played the original I would still recommend Trine 2 as it stands alone well, especially if you’re a fan of platformers or puzzle games.
Trine 2 is available on PC, PlayStation 3 and Xbox360 right now for $14.99, $14.99, and 1200 Microsoft Points. Gane was played on the hard difficulty with around 7 hours of total play time with 23% of the achievements unlocked.
I don’t know why but the way brakes on cars, bikes, etc. has always puzzled me. For nearly all breaking systems in the world the main way they work is by converting your car’s kinetic energy (I.E. its movement) into heat through high friction pads attached to the wheel. This means that, for all practical purposes, the energy that went into creating said movement is unrecoverable and reduces the overall efficiency of the system. I figured that there had to be a better way to do it, one that would at least recover some of the energy lost in order to make all forms of transport more efficient.
Such a system became available with the first electric cars through a system called regenerative braking. The system comprises of a small generator that is attached to an axle or wheel hub that is engaged when braking is applied. This is then fed back into the battery, recharging it and extending the range of the vehicle. These systems are quite large however but I always envisioned some sort of system that could be scaled to fit transportation of any size, and someone has come up with it:
It’s really quite ingenious in its simplicity: braking spins the flywheel which functions as a kind of mechanical battery which can then be used on demand. Of course for a retail system you’d probably want to encase the flywheel in something, for both safety and efficiency purposes, as whilst flywheels are usually safe they can be rather destructive should anything mess with them. Still such a system could be easily scaled up, down or horizontally (use several in one vehicle) to suit almost any application.
There are some issues of course, ones that became painfully apparently back when several countries experimented with a scaled up version of this in the form of the Gyrobus. Granted these were using the flywheels as the sole power source so most of these issues are diminished at lower scales but all the concerns that applied to them still apply to the scaled down versions. Most of these can be overcome though and it will be interesting to see how the idea develops from here.
This is just another example of innovations that should be everywhere. The idea is so simple that it makes me wonder what’s stopping companies from pursuing this idea themselves, like there’s something that I’m not aware of. I’m sure the safety aspect plays a big role but a properly designed and secured flywheel is no more dangerous than a battery of similar size. I’m sure that videos like the one above will inspire companies to look into the idea more closely and hopefully start producing vehicles that are far more efficient than the ones they produce today.
