this game is addictive. they're offering it for free for everyone on the 15th because it's xbl's 5 year anniversary and i thought it wouldn't be too good.

5 hours and 9 achievements later, i proved myself wrong (that's right, i only have 4 achievements to go, weeee).

anyone who has xbl should really give it a try especially since today you can download it for free and have it forever.
