Free first person shooter game software for linux

Alpha Shooter is a 3D OpenGL first-person shooter game with a sci-fi setting.
Alpha Shooter was born as a project for the Computer Graphics course at the University of Bologna.
The main objective was to develop a very simple 3D game using the OpenGL, GLU and GLUT libraries only (and some creativity). Emphasis was not placed on the game itself, rather on learning how to use the libraries to produce a 3D environment and interact with it; it was thus required to build a suitable scenery using polygonal meshes and quadric surfaces, appropriate textures and materials, lights, and effects.
According to my personal taste I chose a sci-fi setting, trying to reproduce an environment that could remind players of a warehouse or loading area located inside a space ship or space station, like those often seen in movies or commercial videogames (of course I was aware of the limits of my implementation). I focused development on a single room, with an outside view, for ease of development (it was my very first attempt at graphics programming) and because it was enough to make use of a wide set of elements of OpenGL, consistently with the project requirements.
The game I wrote was inspired to the First Person Shooter genre, in which the player can move around in a 3D environment, looking around freely through the eyes of the played character, interacting (in very limited ways) with some of the objects present, shooting crates and barrels and some holographic targets.
I had a lot of fun creating that simple game, so after I got my Masters Degree I decided it would be a waste to just leave it hidden in some obscure directory at home; it is now here, released as Free Software, so that I can keep working on it and improving it, with help from whoever will be interested, in the hope that it will be useful as an example on how to get started in computer graphics and games development.
Enhancements:
- Binary packages were created for all supported operating systems, including a Windows installer, an i386 Debian Linux package, and a PowerPC Mac OS X DMG disk image.
- Additionally, the improved persistent mouse movement mode uses a dynamic mouse cursor that shows direction and speed of rotation, making that movement mode more intuitive and useful.
- Several minor bugs have also been fixed.

This is an adapted, improved version of the popular javacave game, written in QtRuby.

Fight Win Prevail (or FWP for short) is a hobbyist multiplayer first person shooter. Fight Win Prevail is set in an imaginary universe where fearless pilots fight to the death with their futuristic vehicles.
Gameplay lies somewhere between the Mechwarrior-series and Quake 3. It is faster and more action-orientated than in Mechwarrior, but tries to avoid the jump-around-like-crazy-and-fire-at-everything-that-moves-gameplay known from Quake 3.
Fight Win Prevail is a pure multiplayer game and does not have a real singleplayer mode. Our primary target are LANs, but the game is playable over the internet, too.
Main features:
- Good graphics, physics, sound, and gameplay (for a hobbyist game)
- Multiplayer over TCP/IP
- 3 types of vehicles with individual characteristics (mechs, hovercrafts, and helicopter-like aircrafts)
- Distinct weapon types (classical projectile weapons, beam weapons, ballistic weapons, etc.)
- Distinct map types (from close combat indoor maps to large landscapes)
- An extendable set of vehicles, weapons, and maps
- 4 game modes (deathmatch, team deathmatch, sole survivor, team survivor)
