Screenshots, in-game Milestones for MX vs ATV: Untamed PSP

Sure, there'll be a lot of high-octane off-road racing in the PlayStation Portable version of Tantalus and THQ's MX vs. ATV Untamed, but that's not all there is to the game. THQ has revealed that the game will also include a PSP-exclusive Milestone system.

Milestones are incentives that allow players to unlock additional content by achieving specific goals in the game. The Milestones won't be limited to World Tour mode, with some Milestones requiring players to play through multiplayer, free ride and other gameplay modes. Progress can be tracked from the game's Profile screen.
