Respawn Entertainment co-founder Jason West left the studio earlier this year due to a conflict with fellow co-founder Vince Zampella, a new report claims.
According to Vanity Fair's sources, Zampella felt that West was "sabotaging the company", following West's supposedly "erratic" behavior during the duo's lawsuit against Activision.
While news of West's departure emerged in March, reports earlier this year suggested that West had been mostly absent from the studio since May 2012.
West and Zampella formed Respawn Entertainment in 2010 following a long running dispute with Activision. Filed in December 2010, Activision's $400 million contract-interference suit alleged that EA had attempted to lure the Call of Duty creators away from Activision.
