Given the immense popularity of the battle royale genre thanks to trailblazing games like PUBG and Fortnite, many are wondering if other games will follow suit and add a Hunger Games-style mode. We know Activision Blizzard is watching the battle royale space, so could Overwatch jump aboard and add a battle royale mode?

Don't get your hopes up. Speaking to Kotaku, game director Jeff Kaplan said he's intrigued by the idea, but pointed out that it would be no small task to get it done the right away. Kaplan, who says he has played "hundreds" of hours of PUBG, said he's concerned that even if Blizzard could do it, that it might not feel right without a lot of work.
