By 2020, the world will be full of people hunting each other and occasionally hiding in bushes as battle royales spill out into the streets. They're already on our phones. So of course everyone wants a slice of the pie that's currently dominated by PUBG and Fortnite. Including Blizzard. Overwatch has already experimented with several different modes, from PvE horde romps to small duels, but a battle royale mode would be a considerably greater challenge. 

“A lot of times when I hear some of our fans pitch it, they’re like ‘Oh, just put a card in the Arcade one day that’s a battle royale mode,’ and I’m like ‘Fuck, that would be awesome,’” Overwatch director Jeff Kaplan told Kotaku. “But there’s a lot of design and tech work to get us to that place and not just feel like a me-too game.”
