Bloodshot Island

"Bloodshot's nanites made him a nearly unstoppable killing machine. His enhanced strength, speed, endurance, and healing made him the perfect weapon, and he served his masters at Project Rising Spirit--a private contractor trafficking in violence--very well. Now, Bloodshot is a shadow of his former self. He lives in self-imposed exile, reeling from the consequences of his past life and the recent events that nearly drove him mad. But when a rash of shootings by gunmen who appear to look just like Bloodshot begin, his guilt will send him on a mission to stop the killers, even if it means diving head-long into the violence that nearly destroyed him."--Back cover of Volume 1.
