Batman - War Games - Book 01 (2015)

Tensions escalate and war comes to Gotham City when Batman is drawn into a skirmish between rival gangs. As Gotham's biggest gang battle ignites, Batman must call on all his available allies-Oracle, Batgirl, Nightwing, Orpheus, Onyx and Tarantula-to preserve life and contain the chaos while trying to determine who started this outbreak of violence. Plus, Tim Drake must abandon his role as Robin and Batman gets an unexpected (and unwelcome) replacement in the form of Spoiler.
