Vince Zampella and Jason West are two of the most important names in the gaming industry. Both of them were ousted from Activision, the company that developed Call of Duty.

Zampella and Jason West are the creators of Modern Warfare and decided to start a new gaming studio company called Respawn Entertainment. Respawn already has a partnership with Electronic Arts now too.

There has been a legal battle over the last month between Activision and Zampella/West. Both Zampella and West sued Activision over unpaid royalties for Modern Warfare 2 and Activision decided to sue them back. Activision accused the men of scheming to “hijack Activision’s assets for their own personal gain.”

Kotaku reached out to Activision to find out their opinion on Respawn’s partnership with EA. Activision responded by saying:
“This agreement comes as no surprise to Activision given the myriad of improper activities detailed in the cross-complaint filed on Friday against Jason West and Vince Zampella. We look forward to continuing to work with Infinity Ward’s deep bench of proven talent on exciting new projects.” [Kotaku]
