Red Planet: Survive Steam CD Key

Red Planet: Survive is a first person survival game for Microsoft Windows. 

Surviving in the harsh conditions of the Red Planet will be hard, but if you are strong enough, you will succeed.

Find the best way to survive, but be careful, since each wrong step will ensure your demise.
The environment is your main enemy. Radiation, low temperatures and the oxygen-free atmosphere will certainly kill you.
The meteorites also pose a threat and may even destroy your base and kill you. There is a chance to see a "burning" meteorite at each 30-50 minutes. When they explode, the parts are scattered over a fairly large radius.
