Trials Evolution

In TRIALS HD, a downloadable game available exclusively through Xbox Live Arcade, players drive motorbikes through fantastical stunt courses as quickly as possible. The bikes move through realistic-looking three-dimensional worlds ranging from war zones to sewage systems, but their movement is restricted to a two-dimensional plane. That means there's no steering. Players simply control throttle and braking and shift their rider's weight forward and back. A realistic physics system (or at least realistic for a world in which you can move only left and right) combined with a rag-doll effect when players crash creates some very painful looking wipeouts. Even if players happen to survive a race unscathed, their rider will likely suffer some form of accident -- like a heap of giant logs falling onto their bike, or an explosion that sends him flying almost all the way back to the start line. Plenty of mini-games, a simple-to-use custom track creator, and support for online play for up to four racers give players plenty of reason to keep playing even after they finish the lengthy and challenging career mode.
