Snowboarder XS is a web flash game published by Catalyst games. The game was also featured on Miniclip for quite some time, but is now unavailable to play due to the site being updated.
Snowboarder XS is a 3D third person snowboarder game where you navigate through a mountain course, sliding down hills, hitting ramps, and performing tricks to score points. The funny part about the game for me at least was how you can wipe out with a funny animation with the character. Once again, another classic game I loved playing.
