Dean Hall will step down from his development duties on DayZ and leave Bohemia by the end of the year.
Speaking to Eurogamer, Hall said his original plan was not to carry on working on the hit Early Access title this year, but said it would be "stupid not to", given the work still to be done on the game.
He stated that creative work on the project would eventually be handed over to the current team he leads, although he'd like to always be involved with the game in some form.
Hall added that once he leaves Bohemia, he wants to start a new game studio in New Zealand
"Originally I wasn't going to do this year, but it would be stupid not to, and it would be unfair to the community," said Hall.
"I have to be on the project as long as it's important to. Whether that role is as the leader, whether that role is in a more creative sense... But at a certain point there will be diminishing returns.
"The thing is, if I'm involved in the project, I'll be fighting anybody on the project to make sure it's good, so for the rest of the year, I'm there. And I don't just sit around; it doesn't matter if I'm the cleaner or the leader or whatever, I will be making sure - I will be in Marek's [Spanel, CEO] office yelling at him. I'm notorious for it."
Open-world zombie survival game DayZ has been a mammoth success since it was released as a mod and then as a full standalone version on Steam in December last year. The mod has been played by more than 1.7 million unique players, while the full game has sold over 1.5 million copies.
