You may perhaps remember that racing/platforming/puzzleish XBLA game Trials HD about injuring yourself on a motocross bike. Its sequel, Trials Evolution seems to be even more genre defying.
Not satisfied with only meshing three unlikely genres together, RedLynx -- the developer behind Trials -- has thrown in first person shooting, arcade shooting, and pinball (that's a genre, right?) as you can see in this video. Fresh from Microsoft's Spring Showcase, these screenshots also show off the new four-player multiplayer -- both local and online -- in depth level editor, and character customisation.
Don't worry, you won't have to wait too long to smash your head against a cliff face with some buddies. Trials Evolution is slated for a spring release.
