Gearheads of War

Holy shit this game is awesome. If you want a retro-remake that doesn't take itself seriously, get this. At first, it's incredibly hard, but as you get the hang of things you feel like a bionic badass, chucking enemies and barrels with abandon! I don't think it has online multiplayer, which is a shame. But it has co-op, plenty of unlockables, and all sorts of good stuff to keep you entertained. Best part about the game: it's 800 MS points.
