Marty McFly has put five free TimeShift maps on Xbox Live. Biff tried to stop him but Doc helped and everything turned out alright in the end.
This Futures-Past bundle is based around the multiplayer side of things, and all fresh locations will be compatible with every game type.
TimeShift came out at the end of last year on PC and 360 but failed to have the sort of impact its time-bending premise had promised. It came out on PS3 a bit later.
