"How does it feel to know you will die on Mars?"
―General Killbane to the Commander.

Mars is the fourth planet from the sun in the solar system. It is the setting of the climax of Gangstas in Space as the antagonist General Killbane sets up his base there to escape the Saints.

It is situated next to Real Earth.

Killbane attempted to milk a cow, but the milk went red and chewed up a branch of berries.

Martians live here and they hate Zin or purple dinosaurs with big noses that go "Meep, I am a hairy willy".

During his presidency The Protagonist went on a mission to Mars and was the first man/woman to step on the red planet. He set up the United Saints Flag on the Martian surface.
