At least another four staff have left Modern Warfare studio Infinity Ward, following the high-profile departure of Jason West and Vince Zampella.
Lead designers Steve Fukuda and Zied Reike have walked according to a report by Kotaku, both of whom had been with the team since it was established in 2002.
Programmer Rayme Vinson and lead artist Chris Cherubini have also resigned from the company. Bruce Ferris, senior animator, left the company earlier in the month to join Big Red Button Entertainment, according to IGN. Activision said yesterday that there remains a "deep bench of proven talent" at the studio despite recent departures.
West and Zampella were sacked by Activision last month, and have since set up a new studio, Respawn Entertainment, bank-rolled by EA Partners. The pair are engaged in a bitter legal battle over royalties and creative control on the market-leading Call of Duty: Modern Warfare franchise.
