Graviton project is a old-fashioned two player space shooter.
Graviton is a game in the style of the old space shooters of the Amiga, such as Bratwurst or Gravity Force 2.
It has been updated with 3D graphics.
Version restrictions:
- This is a VERY early version of this game. There is no network play, no fancy graphics, only one type of ship, one type of gun, etc. And respawning isnt implemented yet, but I consider that to be one of the least of the problems. Rest assured, it will be implemented very soon. First, however, I need some kind of font support to allow the number of lives to be drawn - and therefore texture loading support.

Monkey is a two player game (monkey and hunter):

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.

FlatFrag is a multiplayer action shooter game. With its deathmatch fights it strives to be an entertaining arcade-style experience.
The game is played from a birds eye view and contains some 3D effects in order to make it not seem too flat. Currently only the game mode deathmatch is available, but others will probably be developed in the future.
The game has been built from scratch, though a few important libraries were used in the process. For example, OpenGL is used for fast 3D graphics and SDL provides the game with many cross-platform functions.
It is developed by a single person as a hobby project, but it is released under the terms of the GPL (GNU General Public License), which makes it Open Source software. So everybody is able to get the sourcecode and do his own changes to the project.
Main features:
- Cross-platform support currently for Linux and Microsoft Windows (planned: Mac OS X, BSD, though you can try it anywhere with the provided sourcecode)
- 3D graphics using OpenGL -- the game is played from a birds eye view, but the individual tiles are 3D cubes
- 3D sound using OpenAL -- 2D would probably be more appropriate
- SDL is used for cross-platform input, networking and window creation
- Multiplayer network games with up to 32 players (actually there is no fixed limit set yet)
- Support for Lua-scripted modifications (more like planned, but the console already expects Lua code as input)
- File types: Ogg Vorbis used for sound compression, PNG used for image compression
- Advanced particle system
- Dynamic lighting
- Bots
- Ridable cars and usable stationary guns
- 14 different weapons (some of them very unconventional)
- In-game map editor
- Game modes: deathmatch (more planned)
- Dedicated game server
- A server list function, which fetches a list of servers. You can also see the list of servers here.
- Completely free software -- free as in speech and free as in beer -- Licensed under the GPL

UT2004: SAS is an UT2004 Mod that focuses on the three main SAS units around the world. SAS focuses on the three main SAS units around the world, the British SAS, the Australian SASR and the New Zealand NZSAS who all perform counter-terrorism, operating deep behind enemy lines, gathering intelligence and other duties in various countries.

Their main advesary is OpFor that stands for Opposing Forces who are a collection of the enemies the SAS have faced in past and present times. Their ranks are comprised of regular military, guerilla, terrorist and para-military groups.

Players can choose their in-game player model from a variety of uniforms based on its real world counterpart. From the environment based camouflage patterns of desert, woodland, and jungle to counter-terrorism kits players will have a wide variety of choices. Certain player models feature unique attributes such as body armor, anti-flash hoods and camouflage.

Weapon selection in SAS is done through a loadout system where you can select a primary weapon where your choices are a submachine gun, assault rifle, shotgun, sniper rifle or light machine gun. Secondary weapons include pistols while other parts of the loadout allow you to chose three different grenade types and a knife. Weapons in SAS can kill very easily, some with just a single three round burst.
