SImply put this game is one of a kind from my gaming experience. You can either be the racer and try to avoid traps and being shot, while gaining powerups for your partner and trying to win the race, or if racing isnt your thing and you prefer shooting things or making things explode (which is my fav part) then you can operate various gun torrents along the track and shoot at the other racers, and even the other torrents, to both protect your driver, and take out any contenders for 1st place! and of all the free games i have found on XBLA this HAS to be the best as far as graphics goes, and I could easily have seen this being made into a full sized game.
Only downside i have found is that most of hte time when i try Online play that not many other people are on, if any, but thats probably because not enough people know about it, i only found out aout 2 weeks ago and from what i understand its been free for months. so go out, downloaded and race or shoot stuff up!
