SFX-360: "New to Trials HD for Xbox Live Arcade is the Big Thrills pack, which is a highly addictive add-on. This is the second add-on to the game; I feel Redlynx has does a great job keeping fans coming back for more.
Trials HD has been a really great game to play and learn. It offers many stages that add different versions of difficulty to it. Nearly all maps have their own skill level ranging from an easy holding down the throttle and go, and harder levels that require more precise throttle control and shifting weight to keep your balance."
