The year is 2184 AD.
Mars is newly free, but not safe. A cold war rages between Earth-Mars space. The Martian space-elevator lies in nuclear ruins, a million lives snuffed in its fall.
Gauntwings and space-spheres bristling with Ares-class kinetic-kill shards patrol the Asteroid Belt.
Memetic hacks and information warfare brings chaos to the lives of dome-dwelling Martians and teeming masses of old Earth alike.
Genetically-perfected ninjas assassinate enemies of the state.
...and you hide your past in a claustrophobic orbital warren - Redside Phobos - floating on the edge of Free Mars, drinking yourself to an early death.
