Respawn co-founder and Call of Duty creator Vince Zampella recently talked with IGN to discuss the formation of Infinity Ward and the birth of Activision's wildly popular military FPS franchise, revealing that Call of Duty was created, in part, as a jab at EA and Medal of Honor, which Zampella had worked on at 2015 Inc.

On the latest episode of our monthly interview show IGN Unfiltered , we asked Zampella about where the idea for Call of Duty came from and whether or not it was an "f-you" to Medal of Honor, to which we responded by saying, "a little bit."Zampella then went on to discuss how–following the success of their work on Medal of Honor: Allied Assault–Electronic Arts wanted to take ownership of the studio, something he and his team pushed back against. "Originally when we formed Infinity Ward we were working with EA. We had a deal to do the sequel to Medal of Honor," he explained. "Allied Assault did so well that EA wanted to pull it in house, so they tried to force us to come be part of EA. We didn't want to do that."When the publisher "tried to strong-arm" the studio, Infinity Ward opted to take its business elsewhere and partner with Activision to essentially one-up Medal of Honor with Call of Duty. "Once they tried to strong-arm us, we decided we don't want to be part of EA. As a team we decided that isn't what we set out to do. We ended up going and working with Activision, and yeah, Call of Duty was kind of a response to that," he added.Several years later, Zampella found himself in a similar situation with Activision, and after parting ways with the Call of Duty publisher, he formed a new studio called Respawn Entertainment and reunited with EA. The team is gearing up to launch its next title, Titanfall 2 , later this month. While you patiently wait for its October 28 release, check out our hands-on preview of the campaign , and don't miss our full interview with Zampella when this month's episode of IGN Unfiltered goes live tomorrow.
