Free space 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.

Space Racer project is a OpenGL Car Game in a galactic environment.

It aims to be a clone of the well known Stunt Car Racer developed by Geff Crammond, author of Grand Prix I and II.

To play a 3dfx is recommanded. But TNT and Matrox Cards should now work.

If you have a 3dfx, you can take advantage of OpenGL 1.1 in adding this line in config.h:

#define SP_OPENGL_1_1

Space Mines project is a game where one makes money by building mines.
Space Mines is a game where one needs to make money by building mines and by keeping ones workers happy.
INSTALLATION
make all
make install
make clean
USAGE
Build mines (but not too many) and create profits by selling the ore!
You need to pay your workers wages to keep them happy. Mining on other worlds is a dangerous business, and workers are at risk from exploding mines, radiation leaks, etc.
Version restrictions:
- There is very little error checking for if someone enters the wrong data type (like letters where there should be numbers).
Enhancements:
- Decided to release it to the world
- Made it GPL
- Included some documentation

Alien Blaster project is an action-loaded 2D arcade shooter game for up to two players.

Escape of the Unicorn project is a side-scrolling, 2D flying shooter game.
Welcome to the land of miraculous creatures.
Take a risk and play the game called
Escape of the Unicorn.
You play a unicorn,
a noble and most beautiful animal,
the most beautiful to have ever existed.
Your goal is to escape
from a cave full of monsters and traps.
You can move with the arrow keys and fire missiles.
Every missile can harm a monster if it is aimed well.
Beware of the monsters and lasers.
They decrease your energy when you touch them.
The same happens when you hit walls.
Some creatures may also shoot fireballs.
Be careful at all times.
When you are out of energy,
you die and lose the game.
Enhancements:
- Levels now have more complex shape
- 3 crafted levels
- Per-object speed control, and new types of interactions
- New game objects such as Puff Fish, Wall Spikes, Bloops
- Walls no longer damage player, immunity time much shorter

Sable is a frantic 3d space shooter inspired by games such as After Burner and Space Harrier. You pilot a ship through an obstacle-laden landscape and attack or evade swarms of enemies.

Sable itself is quite easy to play. The arrow keys move your ship, and the space bar fires your cannons. Holding down the space bar produces a rapid-fire effect. Avoid enemy craft, enemy shots, and the pylons. Pylons are destroyable but require concentrated fire to destroy.

Destroying an enemy ship is worth 75 points. Destroying a pylon is worth 200. Evading a pylon is worth 25 points.

Pressing P will pause the game. The R key toggles the "pylon radar" display which can be used to help navigate dense pylon fields.

AstWar project is a terminal based 2D space shooter.
Astwar is a ncurses based simple space shooter; two little ships (asterisks), each on one side of the screen, try to shoot each other.
There is network support with several multiplayer options and user extension with Scheme (via Guile) to program the little ship to do some things automatically are in the works.
Provosional keys for now:
Ship 1:
- UP q
- DOWN a
- FIRE e
Ship 2:
- UP i
- DOWN k
- FIRE y
Enhancements:
- astbeep.c (playsound): added #ifdef __linux__
- shoot.c (shoot): added some #ifdefs
- Makefile.am (astwar_SOURCES): added *.h
- shoot.c (shoot): added new thread for each player sound.
- astbeep.c: added pthread_exit
