Free bubble 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.

Bubble Thing - Inflate things. Pop them to create chain reactions. Meet the boss at the end.

Inflate things. Fast to make them pop. Slow to make them grow. Make chains. Meet the boss. Enjoy the music.

Arrow keys move.

WASD to inflate in four directions.

Popping bigger bubbles will spawn more chain-bullets which will pop other bubbles creating chain reactions. They will also release more collectables which net you a greater score.

This game was programmed during the three-day Toronto Game Jam, 2006. I started with my framework, a song, and an idea.

Aquatic Bubble is a nice arcade game.

In Aquatic Bubble you must eliminate all the enemies of the level.

In order to do it you must shoot against them until catching them in bubbles and soon... "to make them burst".

Frozen Bubble is a game in which you throw colorful bubbles and build groups to destroy the bubbles.
In 1p mode, destroy all the bubbles to access the next level. In 2p mode, have your opponent die before you.
Enhancements:
- This release should fix all the bugs encountered in 2.0.0 (all reported aborts should be fixed).
- A few interesting small features have been added.

Torrent Bubbles is an easy-to-use BitTorrent utility program which can search for torrents on the Web.

The main goal of Torrent Bubbles is simplicity, with only a search bar, two buttons, and the ability to double click a search result (to launch a download).

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.

Alien Swarm is an overhead view tactical shooter modification for Unreal Tournament 2004. Alien Swarm is set in a distant future, the players take the role of a Commander in the Interstellar Armed Forces.

They must guide their squad of marines through Swarm infested colonies, overrun bases and outposts, to achieve a variety of objectives. Featuring Assault Rifles, Heat Tracking Guns, Sentry Guns, Flamethrowers and more.

The top down, tactical shooter can be played by a maximum of 6 players in a co-op style. (You can play 8 in total, but then the game gets a bit crowded so we made it 6 by default.) Choose from eight marines, with different specialties - medical, technical, explosive or weapons specialists.

It features a single mission mode and a campaign. Fight off the Swarm to increase your skills and earn medals for extra skill points.
