The weird thing about M.A.R.S. is that it is very different from the typical top-down or side-scrolling space shooter in that your ship is very much at the mercy of the gravitational fields surrounding the ridiculously close planets. It is very easy for your ship to go spinning out of control, making navigation a significantly large part of the challenge. To make matters worse, bumping into a planet causes damage, but that is just all part of the fun of M.A.R.S.
Some of the outstanding features of M.A.R.S. include:

Colorful 2D graphic artwork with shader support and cool particles single player and multiplayer functionality online multiplayer matches aggro-system artificial intelligence for bots lots of awesome weapons, such as AFK-47, WT-Flamer, Flubba, and Fist of Ali special abilities: heal, blast, freezer, and fire wall customizable ships space-age symphonic metal soundtrack, composed by a Hungarian band called Obsidian Shell. Multi-language support keyboard and joystick input match customization

M.A.R.S. has a good mix of game styles that should keep the attention of gamers, particularly for multiplayer matches.  Among the game types are:

Deathmatch – The rules are simple: kill or be killed. Spaceball – protect your planet from the sphere of death Teamdeathmatch – team up against your common enemies Grave-itation-pit – make use an instant kill projectile, but be mindful that it is very sensitive to gravitation, making it difficult to navigate Cannonkeep – capture the remote control (like capture the flag)  and use it to aim a huge cannon at your opponents’ planets rather than yours.

Believe it or not, there is actually a back story to all of the action. The year is 3547, and you are a fighter pilot in a war raging between several colonized planets. Your mission is clear: protect your home planet at all costs, even if it means the total annihilation of your enemy’s planet (something you can actually do in Cannonkeep).

OK, so the story is not exactly going to captivate you, but the gameplay just might. M.A.R.S. is an exciting trip into a world where gravity is king and the best weapon you have is your mind. What it lacks in story depth, it more than makes up for in action and strategy. M.A.R.S. A Ridiculous Shooter is free and open source software and has already made its way into some Linux distribution repositories.  You can also download the game free of charge for Windows, Mac OS X, or for any other platform, if you are willing to build it from source code.  For screenshots and a look at gameplay, including a video of some adorable children playing the game, head over to the M.A.R.S. website.
