After going head to head with Deathstroke, Batman must do the unthinkable to stop Gunhawk from murdering J. Devlin Davenport: use a gun.
Gunhawk moved in on the millionaire as Batman battled Deathstroke. Robin and Oracle figure out the originator of the contracts - an aging millionaire on his deathbed. He wanted to outlive his competition, but he died before the police could arrive. Batman defeated Deathstroke; Essen-Gordon and Bock apprehended Gunhawk.
