Grid Wars 2 is a space shooter arcade game.

Grid Wars2 is basically a PC version of the popular Xbox 360 game, Geometry Wars. Made by Mark Incitti, this release features less special effects compared to the original but also new controls to cater for players who do not own a dual analog joypad.

Your small ship sits in a one-screen grid and vectorized enemies spawn to attack. Use your any-directional gun to stay alive while you rake in points. Along the way a few power-ups will give you a hand, and theres always the emergency screen-clearing bomb you can unleash.

The hybrid option control allows a player to use both mouse and keyboard for ship movement as well as aiming their shots.

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

Magnificent Gunbright is an abstract shooter; destroy the black ball. An Abstract Shooter Developed For Ludum Dare in 48 Hours.

You are the flashy white blob at the bottom, with the clump of other white blobs following you around.

You have the ability to fire the blobs from your cloud at the flashy blob surrounded by a cloud of black blobs at the top of the screen.

If a black blob and white blob collide, both are destroyed. The object is to hit the evil flashy blob at the top of the screen to destroy it.

Falling from the top of the screen like rain is a steady supply of more blobs. If one of the blobs in your cloud touches a white blob that fell from the sky, even while shooting, the blob joins your cluster.

Falling from the bottom of the screen is black blobs, that your enemy can use to bulk himself up, as well. Blob rain does no damage to either party; you can tell that its rain and not bullets because rain travels away from you.

Use the arrow keys to move, and the space bar to shoot.

Once youve destroyed one evil black blob, you will face another, more powerful one! And so on forever until you eventually die.

Destroy the evil black blobs and save the League of Confederated Planets!

Chromium B.S.U. is a fast paced, arcade-style, top-scrolling space shooter.

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.
