Maniac, Hammerhead, Shakespeare, Superstar and Gunslinger -- brought back to life from a comatose state by Omen Enterprises with bleeding-edge technology neural implants that allow them to mimic Harbinger abilities one at a time. Their mission: to oppose the machinations of Toyo Harada and the Harbinger Foundation. Together they make up the elite of the Harbinger Active Resistance Division -- the H.A.R.D. Corps!
Tensions run high when the team starts breaking in Maniac's new replacement. Flatline's first day back to life in the H.A.R.D. Corps may just be his last when things go disastrously wrong during his first live fire exercise.
