This game is awesome, well, for about 20 minutes or so. It's called Doritos: Dash of Destruction, and it's on XBOX Live Marketplace for free! The idea of the game is you control a T-Rex who goes around smashing up an area and trying to stop cars who are collecting doritos. Alternatively, you can also play as the cars who have to collect said doritos and dodge the T-Rex. Along the way you also get some small enhancements which basically turn you into this truck or a mecha T-Rex, depending on who you're playing as. Along the way you get some AI opponent who's also trying to do the same as you, so you have to beat him by doing it faster then he is. Best of all though, this is the most easiest 200 gamerscore points you're going to score in your life. I cleared the whole game in about 20 minutes. The multiplayer isn't so bad actually, and with 3 other friends I can imagine it being pretty fun. There is one achievement where you have to win a game of multiplayer, but this can be achieved by turning on controller 2 and just leaving it there. It's a shame this game doesn't have online multiplayer, actually, because I probably would end up playing it more online. Alas.
