David Goldfarb, the lead designer for Battlefield 3 and Battlefield Bad Company 2, has left DICE.
Goldfarb has previously worked at Guerilla and milestone, but is best known for his work on BF3.
There is no word from the studio or EA of who will replace the developer.
"It was time to move on for me," Goldfarb told Kotaku.
"Fans have nothing to worry about."
Goldfarb did not say if he had another job lined up, but in a blog post said he is working on a movie script.
"Five years, four games," he said, bidding farewell on twitter.
"Grateful to have worked with such awesome people on awesome games. Farewell + Onward."
