The outlaw McCree back at it again in this short Webcomic
Background: McCree was originally part of the Deadlock Gang, who dealt with trafficking illegal weapons. Caught by Overwatch, and shut down for good, McCree's special abilities and marksmanship gave him a second chance and joined Blackwatch (Overwatch black ops devision). Teaming up with Reyes and his guys to do the "dirty" work for Overwatch, McCree was out to right the wrongs he's done in the past. When Reyes wanted to abandon Overwatch and take it over, McCree wanted no part in it. He then disappeared and resurfaced several years later as a gunslinger for hire.
My Thoughts: It is unclear if this comic is before or after Overwatches fall. I feel it might be after due to the fact he's hitchhiking on a train and there seems to be no sign of a Blackwatch task force. Hopefully we'll see what Talon was after in a later comic.
