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 4 player multiplayer—both local and online— in depth level editor, and character customization.
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.
