Brendan Green, the "PlayerUnknown" of PlayerUnknown's Battlegrounds, recently announced that after five years of working on PUBG, he's moving on to something else. He's remaining at PUBG Corp, however, at the head of a new division called PUBG Special Projects, which he said "will explore new possibilities of interaction and connection within the game space." 

Multiplayer is clearly the focus, based on that statement, but Greene recently told GamesIndustry that one thing he's not interested in doing is making a sequel to PUBG. "The last man standing concept is great, but I've done that. I don't really intend to make PUBG 2," he said. "I've done battle royale, it's time to try something else. There are ideas about how we connect to people and how we provide the different experiences I have."
