Free shooter 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.

rRootage is an abstract shooter game. It was created by Kenta Cho and ported to Linux by Evil Mr Henry.
Debian distro: apt-get install rrootage.
Installation:
Download the data files, and the executable for your platform. Put rr in this directory.
On most systems, simply open a console, switch to root, and run ./install.sh. If that doesnt work, you can install manually. Copy rr_share/* to /usr/share/games/rRootage, rr to /usr/bin and make sure everything works.
Running:
Type rr to start the game. The command-line line switches listed in readme_e.txt should all work.
Compiling:
Install the OpenGL development libraries. (This is the hard part.)
Install libBulletML. (http://user.ecc.u-tokyo.ac.jp/~s31552/wp/libbulletml/index_en.html Compiling should be simple. Copy the resulting .a file to /usr/lib)
Install SDL_mixer.
Compile with "make -f makefile.lin"
The file "rr" goes in your path, and all directories except src go in /usr/share/games/rRootage. src is unneeded after compiling.
Uninstall:
Remove the directory /usr/share/games/rRootage, the file /usr/bin/rr and the file ~/.rr.prf.
Enhancements:
- This only updates the packaging.
- Dont bother upgrading if your copy works.

TUER is a 3D FPS written in JAVA + JOGL + JOGG.

TUER is a very small first player shooter. You can shoot robots in a museum with your rocket launcher. It uses a kind of dynamic lighting. You can also perform screenshots and snapshots.

Stargun project is a 2D space shooter game.
Stargun is a space shooter, vertical scroller game. Its platform independent (or at least it is the objetive). The target OS are Windows and Linux. There are plans to port Stargun to BeOs, FreeBSD and Amiga.
Stargun is written in C++ and uses SDL library.
This project is under GPL lisence.
Enhancements:
- Music & sound added
- Joystick support
- Levels support
- some bugs fixed

Offender project is an entertaining 2D space shooter written in GTK+ C for linux.
Its was written casually by Silas and Dylan Albrecht over a one and a half year period with a few large breaks. Before 0.1 was releashed Offender hadnt really been hacked since early 2001 except for a few minor romps.
Offender has been tested under RedHat Linux 7.0 (using kgcc) with GTK+ 1.2.8 and RedHat 7.3 with GTK+ 1.2.10.
If you dont have GTK+ you can get it at gtk.org. If you can/cant compile it in a different environment wed be interested to hear about it through email.
Enhancements:
- Major update release version 0.2
- Much needed feature additions, stable but messy code.
