Former Call of Duty lead designer Todd Alderman has returned to Infinity Ward, nearly five years after he left and then sued Activision.

Alderman was one of the 38 Infinity Ward employees that sued Activision in early 2010, seeking between $75 million and $125 million for unpaid bonuses for work on Call of Duty: Modern Warfare 2.

He followed Infinity Ward co-founders Jason West and Vince Zampella to Respawn Entertainment (Titanfall) but left in 2012 to take a position as a game designer at Riot Games (League of Legends).

"The chance to come back to Infinity Ward and Call of Duty is something I didn't think would ever happen," said Alderman.

"It's been five years since I've been here and a lot has changed. There are a lot of new faces and motivated people who want to make something great. It's a really cool game concept that I want to be a part of. I can't wait to see what we do with a three-year dev cycle.

"I'm excited to be back."

Call of Duty is now on a three studio rotation, with Treyarch providing this year’s entry and Infinity Ward scheduled to produce a game next year.
