Mike Kulas, the founder and president of THQ studio Volition, has announced his retirement from the group.
Kulas, 49, said his decision to leave was not triggered by any changes at the studio or THQ. He added there was little chance he would return.
He told regional paper News Gazette he had been pondering retirement in 2010. He “intends to stay” in Illinois area, where Volition is based, and wants to "clear his mind” before deciding his next play.
Volition’s longstanding vice president, Dan Cermak, will replace Kulas, the paper said.
Kulas co-founded Parallax Software in 1993, before splitting the firm into Volition here years later.
In 2000 the studio was acquitted by THQ.
The studio works on key IP for THQ, building games such as Red Faction and Saints Row
At the end of March, THQ made 16 Volition employees redundant, but Kulas does not expect further layoffs in the short-term.
