Vince Zampella, who had a major hand in developing franchises like Medal of Honor, Call of Duty, and Battlefield, died in a car crash on Sunday, NBC Los Angeles reports. He was 55.

NBC Los Angeles and CBS Los Angeles report California Highway Patrol responded to a single-car crash at around 12:45PM local time on Angeles Crest Highway in Altadena. An Emergency SOS request came in via satellite from an Apple device, according to the CHP’s incident log.

The Highway Patrol did not identify Zampella, but CHP officer Marissa Mcintire sent over a press release about the crash that says:

Preliminary investigation indicated Vehicle #1 was traveling southbound on Angeles Crest Highway, approaching MPM 62.70, within the #1 lane. For unknown reasons, the vehicle veered off the roadway, struck a concrete barrier, and became fully engulfed. The passenger was ejected from the vehicle and the driver remained trapped. Both parties succumbed to their injuries.

Zampella co-founded Respawn Entertainment, which EA acquired in 2017 and is known for series like Titanfall, Apex Legends, and Star Wars Jedi. EA put him in charge of the Battlefield series in 2021 after the rocky launch of Battlefield 2042, and the series’ latest entry, Battlefield 6, has had a strong release. Before founding Respawn, Zampella helped co-create the Call of Duty series at Infinity Ward, where he served as Studio Head and CEO.

EA didn’t immediately reply to a request for comment.
