DayZ Creative Director Brian Hicks has announced that he is leaving Bohemia Interactive sometime in the weeks following the released of update .63. According to a blog post on the DayZ forums, Hicks writes that he feels he is no longer needed for the game's future as the team remaining "has a solid grasp of what DayZ is and what it needs to be".
DayZ has been my life, made my life - and been so ingrained in who and what I am that I won't be able to just walk away. Hell, I've just crossed 7,000 hours between two accounts. From here, I look forward to opportunities back home in the States, being closer to family, and playing DayZ as much as I possibly can. I certainly have not forgotten my promise to TSM Smak to do a 24-hour stream when DayZ hits 1.0.
