That it's gonna be a sick game. Similar to Borderlands and Fallout.
It has a single player mode which can be co-op offline.(story mode) Awesome weapons such as an RC cart with C4 strapped on. There is going to be a multiplayer but im not raged up about that; It's going to be like mario karts but with bigger better everything ;]
Here's some teasing gameplay: http://youtu.be/a6y48hJTpiI
