The breach of contract suit claims West and Zampella held up development on other "Call of Duty" games to try to gain more money. The company is seeking to withhold additional payments to the men, who they claim also kept bonuses from Infinity Ward employees.

The men "morphed from valued, responsible executives into insubordinate and self-serving schemers who attempted to hijack Activision's assets for their own personal gain and whose actions threatened both the future of the Call of Duty franchise and future of Activision's (Infinity Ward) studio," the complaint states.

Activision's filing seeks to show the firing was justified and claims the men met with a key gaming rival, which it says was one of several violations of their employment contract
