Tracer's time as an Overwatch agent is up. Five years after the ratification of the Petras Act, she now tends to small–scale crimes as a part–time hero. But when a punk-rock omnic named Iggy shows Tracer the dire living conditions that have been forced upon London's omnics, Tracer becomes determined to help in any way possible—even if it puts her back in the crosshairs. Acclaimed Eisner and Harvey award–winning writer Mariko Tamaki (This One Summer, X-23) and kinetic artist Babs Tarr (Batgirl, Motor Crush) are joined by exquisite colorist Rachel Cohen (Snotgirl) and letterer extraordinaire Deron Bennett (Tale of Sand) for a bi-monthly, five-part digital series that will be available online for free, starting this December. Working in close collaboration, Blizzard Entertainment and Dark Horse Comics present Overwatch fans with an exciting new addition to Overwatch's expanding story in the limited series Overwatch: Tracer — London Calling. Set several years after Overwatch and its agents are declared "illegal" this essential tie-in comic series will forever alter Overwatch history!
