Overwatch has always stood out in the online shooter arena for offering a surprisingly deep world and diverse cast of characters. But if you haven't been reading Dark Horse's Overwatch tie-in comics, you haven't been getting the full story on this colorful, hyperviolent universe. Fortunately, the latest digital-first Overwatch comic, Tracer: London Calling, is finally making its way to print. IGN can exclusively reveal that Overwatch: Tracer - London Calling will arrive in bookstores on September 28, 2021.
