Intense Deathrace 2000 style game with several game modes than just racing. Multiplayer plays great with the caveat that game ends if one disconnects.

Original Quake maps translated to the HL1 engine. Great fun even after all these years.

Multiplayer is supported by Game Ranger, but there is no lobby or matchmaking. This can only be played in multi by appointment with a friend.

Amazing combat with streamlined modular building. Also you can MAKE GUNS. Hells yeah. People still play this on occasion, but not offen.
