The creator of battle royale progenitor PUBG Brendan "Playerunknown" Greene has departed Korean games firm Krafton.

The developer has founded a brand new studio called Playerunknown Productions, which is based in Amsterdam in the Netherlands. That's where Greene has been based for around two years now heading up the Special Projects team under the Krafton umbrella.

Krafton has taken a minority stake in Greene's new outfit.

Playerunknown Productions is apparently working on systems that will allow "massive scale within open-world games." When he set up Special Projects, Greene said that he was done with the battle royale genre and instead wanted to work on something new.

"I'm so very grateful to everyone at PUBG and Krafton for taking a chance on me and for the opportunities they afforded me over the past four years," Greene said.

"Today, I'm excited to take the next step on my journey to create the kind of experience I've envisaged for years. Again, I'm thankful for everyone at Krafton for supporting my plans, and I'll have more to reveal more about our project at a later date."

Greene joined Krafton in South Korea in 2016 heading up development in Playerunknown's Battlegrounds. That title was released in early 2017 and to date has sold over 70 million copies. Special Projects was working on another title called Prologue, though it's not clear what's happening with that game.
