The Overwatch comics site has been updated with a new one called "Searching" that features everyone's favorite Russian tank, Zarya. The comic begins where the Sombra cinematic video left off as Zarya goes on a hunt to find the hacker extraordinaire.
You can read it on the Overwatch comics site, though an interactive narrated version should show up soon as well.
Here's Sombra's video in case you want a refresher of the events prior to the start of Zarya's comic.
