DoomRL (Doom, the Roguelike) is a fast and furious coffee-break Roguelike game, that is heavily inspired by the popular FPS game Doom by ID Software.

The game is free. But you can make a donation at the official site.

Note about the Linux versions — you’ll need SDL, SDL_mixer, SDL_image and libpng installed, and smpeg. On some linux distro’s mp3 support is not enabled in SDL_mixer — a workaround has been posted on the forum

Note about the Mac OS X version — If you have your Mac configured to accept only signed apps, you’ll need to manually allow DoomRL to run after installation (Ctrl-Right click the App and choose Open) — if you have any problem installing, feel free to ask at the forums!
