5 Another game of the year contender by far.MarkeyMan90 | 20/04/2011 | See all MarkeyMan90's reviews (19)I will start in saying that this is the best game I've played all year, I haven't completed it yet but from what I've played, it's quite simply astonishing.I've played this on the 360 aswell and I can tell you now that Valve have done a steller job on the PS3, in terms of graphic's it's alot crisper and you also have the Steam compatability. You get a free Portal 2 download on Steam for your PC with the PS3 version so that co-op can somehow be played between PS3 consoles and on PC's.Puzzle's are still brilliant that really make you think and are so fun to work out. You now have these sort of gel-like substances with each giving you different abilities. The orange coloured gel increases your speed while blue lets you bounce up high and the white gel makes any surface portal-able.So overall, it has some of the best voice acting I've ever heard in a game with a supurb performance by Steve Merchant who voices the little personality sphere who is hilarious at times due to great writing. Top notch graphic's (namely for PS3), sound is amazing, PS3 version has Steam capabilities, it has a brilliant central mechanic with it's portal device and I can't think of single negative for the PS3 version. Now it's just up to you to get this game.
