Set in a futuristic utopia, an elite peacekeeping force thwarts the rumblings of civil war. But deception within the ranks has caused two members of the most feared unit, Dead Echo, to strike out on their own. Now washed-up mercenaries turned space pirates, Grayson Hunt and Ishi Sato's latest quest for a quick buck goes south. Stumbling upon their ex-commander's warship, the Ulysses, Grayson engages this behemoth head-on. Outmanned and outgunned, his only option is to ram the Ulysses in a suicidal bid at redemption. Narrowly surviving a crash landing and now stranded on the abandoned paradise planet of Stygia, Grayson and Ishi find themselves surrounded by hordes of mutants and flesh-eating gangs. They survive on two objectives: get off the planet alive and exact revenge on the man who sent them there.
