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.

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.

Save The Penguins is a crazy space shooter with penguins and flying saucers.
This is inspired by "Save The Gweeks" for the Archimedes, in which you saved the gweeks from the snerds. I havent had access to the original, so how close it is I couldnt say.
You control this sphere/circle/whatever with the mouse. Left click to acellerate towards the cursor. Right click to fire lasers. Middle click to pause. Esc to Quit.
The idea is to kill the space ships before they either kill you or all the penguins.
The art for the penguins came from Pingus, the tileset was ripped from supertux.
If anyone would like to contribute levels/art/sound that would be cool.
Main features:
- Scrolling, moving and shooting.
- Tileset defined in simple configuration file
- Loading/Saving level to file with in-game level editor (press E).
- Objects (that is, non-static ones) get damaged when you hit them. The penguins explode in a pile of blood.
- Reasonable collision detection - you have to at least try to get it stuck.
- NEW!! Nice particle-based explosions. Saves me both needing a graphic for it, and it looks pretty cool
- NEW!! Powerups. Dont do much atm. One heals you, the other two hurt you by different amounts. Theres a hook to attach a sound to powerup/powerdown for when I get round to it.

Scum of the Universe is a space trading game that combines two genres: arcade and strategy. On one side, its a classic vertical-scrolling space shooter game. On the other side, it is an adventure and strategy. You should choose whether youll be an independent space trader, firearms smuggler, fierce freedom-fighter or something in between.

Following the main storyline, you go through the galaxy from one planet to another. Space travel requires fuel, so you need to keep earning money to buy it. You can also buy various upgrades for your spaceship and weapons that affect the arcade part of the game. The storyline itself is not linear. There are also some points where youll need to make decisions that will determine your destiny.

For thousands of years, people of planet Xen have colonized the planets in their galaxy. As time went by, many colonies grew unhappy about their status, as everything was controlled by Xen. Some of them organized military units and declared independence. You can see the status of each planet by "Rebel Sentiment" indicator. Planets with RS higher than 50% are ruled by the Rebel government, and Rebel laws apply.

Trading firearms is legal on planets ruled by Rebels, as they need as much firepower as they can get. On the other hand, Empire forbid all the trading with firearms and other ground weaponry as they wish to maintain their military advantage. One of the ways to make a lot of money is to buy cheap guns at Empire planets and sell them for a lot of money on Rebel planets where demand is extremely high. But be careful as youll need to fight Empire fleet once they find out youre a smuggler.

Beside the raging war between Xen Empire and the rebels there is increased activity of alien species, who destroy human ships. The stronger alien activity, the more waves of alien ships youll need to defeat in each planets outer orbit. Some of the aliens you destroy may drop artifacts (big blue ones) which you can sell at any space station for 20credits a piece.

Blob Wars : Blob and Conquer is a 3rd person action shooter. With the apparent defeat of Galdov and the reclaiming of the Fire, Space, Time and Reality Crystals, the Blobs battle was only just beginning.

Gammarace project is a vector graphics shooter.

An ode to oldie but goodie. It is a simple game that you can jump into and out of with no instructions. Just attempt to achieve the highest level possible (20 is about the highest unless you are some android from the future bent on killing us.

It was programmed in "D", digitalmars.com. What I consider the replacement for C/C++ and Java.

Anyway, just have fun.
