Free 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.

Installation:

download
chmod +x snake(gl).rb
run it.

Open Space Shooter is a simple 2D space shooter like asteorids.

Just a small spaceship, some Asteorids and some enemies. You got lasers and rockets and try to fight the enemy ships, not more.

It is simple but funny.

All is just a prototyp of a game I want to write later. But I have no time at the moment...

A Jacks Game is a real-time game that runs in a Web browser using the AJAX (Asynchronous JavaScript and XML) technology.

Multiple users can login in A Jacks Game to explore a common map and earn a common currency as their score.

A Jacks Game is free software released under GNU/GPL Open Source License.

Chess::Game is a class to record and validate the moves of a game of chess.

SYNOPSIS

use Chess::Game;

$game = Chess::Game->new();
$clone = $game->clone();
$move = $game->make_move("e2", "e4");
$move_c = $clone->make_move("e2", "e4");
$true = ($move->get_piece() ne $move_c->get_piece());
$move = $game->delete_move();
...
while (!defined($result = $game->result())) {
# get a move
$move = $game->make_move($sq1, $sq2);
if (!defined($move)) {
print $game->get_message();
}
}
if ($result == 1) {
print "White wins!n";
}
elsif ($result == 0) {
print "Draw!n"
}
else {
print "Black wins!n";
}

The Chess module provides a framework for writing chess programs with Perl. This class forms part of that framework, providing move validation for all moves recorded using the Chess::Game class. The Game contains a Chess::Board, 32 Chess::Pieces and a Chess::Game::MoveList that contains a series of Chess::Game::MoveListEntrys that record the exact state of the game as it progresses. Moves can be taken back one-at-a-time to allow for simple movelist manipulation.

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.

Spout project is a simple abstract caveflier/shooter game.

It was originally written for a handheld LCD console, then ported to Windows/SDL, then to Unix/SDL.
