Damn, not a great week for Activision indeed. So the previous heads of Activision, Vince Zampella and Jason Westare, are now filing a lawsuit because they claim that Activision fired them before they could get their scheduled “royalty payments” from Activision for Modern Warfare 2′s profits.

Attorney Robert Schwartz said, “Instead of thanking, lauding, or just plain paying Jason and Vince for giving Activision the most successful entertainment product ever offered to the public, last month Activision hired lawyers to conduct a pretextual ‘investigation’ into unstated and unsubstantiated charges of ‘insubordination’ and ‘breach of fiduciary duty,’ which then became the grounds for their termination on Monday, March 1st.”

Activision said the following in response:

“Activision is disappointed that Mr. Zampella and Mr. West have chosen to file a lawsuit, and believes their claims are meritless. Over eight years, Activision shareholders provided these executives with the capital they needed to start Infinity Ward, as well as the financial support, resources and creative independence that helped them flourish and achieve enormous professional success and personal wealth.”

In return, Activision legitimately expected them to honor their obligations to Activision, just like any other executives who hold positions of trust in the company. While the company showed enormous patience, it firmly believes that its decision was justified based on their course of conduct and actions. Activision remains committed to the Call of Duty franchise, which it owns, and will continue to produce exciting and innovative games for its millions of fans.”
