The player takes the role of an astronaut with the mission to find a habitable planet, after humankind plunged the Earth into an ecological catastrophe. The player is not on their own, but accompanied by programmable robots that can help in building and defending structures. Through a satellite link with 'Houston' she/he is directed to complete a number of missions on different planets.

Limbs Off			phun-fysics, Fighting	Limbs Off Genres phun-fysics, Fighting Latest release 2012-05-23 Developers plaimi Code license GNU GPL 3 P. languages C++ Libraries OpenGL, SDL, LibPNG, Fontconfig Contribute Limbs Off is a free game. This means that the source code is available to be studied, modified, and distributed. Most projects look for help with testing, documentation, graphics, etc., as well. Limbs Off is the flagship in plaimi's phun-fysics genre, in which they strive to reproduce complex real life physics, but take certain liberties whenever they feel it will add to the entertainment of the games. Limbs Off specifically is a fighting game that takes place in space. Right now there is only one planet and three characters, but plaimi want to implement several planets as well as inter-planetary travel via cannons, amongst other features. The characters are "limbless", and consist of a head, body, two feets and hands. As of yet, the only way of "fighting" is running into each other. When the characters hit each other, their mass is decreased up to a point where their body parts are unlinked and the characters effectively become space junk. The source code is licensed under the GNU GPL, and plaimi encourage people to contribute with code, make their own art, and make packages for UNIX package managers. Limbs Off does not come with sprites or sounds. Instead, plaimi want to hack the game to load art from a data directory, so that users can install their own art. As of yet it only supports this with character sprites, as the game is at a very early alpha stage. It "went public" on the 24th of September in 2011, on github. The game runs on relatively modest hardware, and has been compiled and run successfully on most modern UNIX-based operating systems.
