This news was announced to celebrate the great success of the side-scrolling Excitebike-style platform/racing/puzzle game series which has sold an amazing 4 million units since the release of Trials HD in 2009 for Xbox Live Arcade. Its sequel, Trials Evolution was so successful it hit a launch-day sales record for Xbox Live Arcade when it was released last year (2012).
Trials Evolution Gold Edition will include the complete Trials HD game alongside every track from Trials HD. Additionally the retail game will come in a steelcase box and include the game’s official Trials Evolution Soundtrack. Also included will be a Gold Bike, Gold Wheels and Gold Rider Outfit.
