Postal 2: Share the Pain DEMO is a FPS game for Linux.
"Share the Pain" adds multiplayer gametypes to the previously single-player only Postal 2, with its mature-rated attitude (Capture the Flag is called "Snatch", and involves stealing the other team's, uh, mascot...you get the point). The multiplayer gametypes are fully network compatible with the Windows players.
The package contains a complete DEMO version of the game, featuring one abbreviated single player level, and a few multiplayer maps for your enjoyment. The full, commercial version of Postal 2 for Linux will be available soon (and rumor has it there will be a Linux boxed version, so please don't run out and buy the Windows version in preparation just yet). The package also contains the Linux dedicated server.
Postal 2 has some rather explicit content. Don't download it if you're a small child or easily offended.
