M.A.R.S. is a native Linux game for two players, flying with ships in a two-dimensional space setting, governed by the laws of gravity. There are several game modes. For instance, when playing “SpaceBall”, each player aims to destroy the home planet of the other by dropping a huge ball at it. In order to avoid him doing so, there are several weapons, suitable for different situations.

Mars Core team builds a PPA for Ubuntu 10.04,10.10, and 11.04.
Run the commands in terminal:

sudo add-apt-repository ppa:mars-core/ppa
sudo apt-get update
sudo apt-get install marsshooter

If you want to surf on cutting edge, you may install marsshooter-svn instead of marsshooter. This will install the latest SVN-build on your computer. But this will be even more buggy, then the “stable” release.

For those, how want to develop with SFML2, there is a package libsfml2-dev in this ppa, which will install the headers of SFML2 on your system.
