Until I saw this video of the Overwatch voice actresses swapping voice lines, I didn't know that I needed to hear Symmetra say "It's high noon." Polygon recently got the voices of Symmetra, Sombra, Mercy, and Pharah together to say some of the most famous lines from the game, specifically the ones that their own characters would never say.
Recently, Andrea Toyias, Senior Casting and Voice Director at Blizzard and person who holds some of the coolest panels at BlizzCon, tweeted about an article at Rolling Stone covering Overwatch. I think it's one of the most succinct ways to describe the Overwatch phenomenon in terms of its ubiquity.
If you remember a while back we did a post about Overwatch's voice actors being kinda silly.
