The sequel to the popular and critically acclaimed Trials HD is now available for download on the Xbox Live Arcade. Trials Evolution features outdoor environments, local and online multiplayer, and track-sharing.

The original Trials HD was released in 2009 and quickly became a classic due to its addictive gameplay and high difficulty level. The game is a physics-based motorcycle game in which players are challenged to make it across indoor “tracks” filled with traps and physics puzzles. Mastering Trials HD required great amounts of precision and patience.

Trials Evolution looks to build up on its predecessor in every way possible. The tracks are no longer confined to indoor spaces and now contain curved driving lines. Players can play with up to four of their Xbox Live friends online or locally on any track, racing each other or, I assume, cooperating to overcome tricky puzzles that require more than one player. The track editor is back, and now players can share their self-made tracks with others using the new “Track Central.”

Fans of the series and those curious about Trials Evolution can play a trial version of the game for free or download the full game for 1200 Microsoft Points (about $15.00). With the tight gameplay and high replay value apparent in the Trials series, I’d say that price is a steal compared to many lackluster $60 titles I’ve played.

Check out the launch trailer for Trials Evolution below. Based on what I’ve seen, the game might be Xbox Live Arcade game-of-the-year material.
