Tux Racer

TuxRacer is a 3D racing game featuring Tux, the Linux kernel mascot. Gameplay consists of sliding down a snowy slope, avoiding hazards like cliffs, ice, and trees, and collecting herrings. TuxRacer was followed by Extreme Tux Racer, which forked off from the original after development ceased in favour of a proprietary commercial release by Sunspire Studios.
