Books like Rogue Trooper: Tales of Nu-Earth, Vol. 1

The war between the Norts and the Southers chemically poisoned the entire atmosphere of Nu-Earth, so the Southers created the Genetic Infantrymen: blue-skinned soldiers who could breathe the toxic air, equipped with bio-chips to record their personalities in their final moments, for eventual re-corporation. But a Souther traitor sold the G.I.s. out, and all but one were slaughtered. Now this survivor stalks Nu-Earth on a mission of revenge, aided by his dead friends now "living" in his gun, helmet and backpack. He is the last G.I.--the Rogue Trooper! Suggested For Mature Readers.
