Patrice Désilets is no longer part of Ubisoft (again), as reported on Kotaku, where they quote Ubisoft making this sound like a fairly amicable split based on creative differences, and quote Désilets saying he was fired, and he intends to fight the situation. Désilets was Creative Director for the Assassin's Creed series before leaving Ubisoft in 2010, going on to sign with THQ, though he would have to wait for a non-compete clause to expire to join the new THQ Montreal studio (spending some of the idle time poachng old colleagues). Patrice then joined THQ, only to find himself drawn back in Michael Corelone-style when Ubisoft acquired THQ Montreal. This brings us to today, and Ubisoft's statement to Kotaku explains the company and Désilets didn't see eye-to-eye on his role, and sort of implies the parting was a mutual decision: "Unfortunately, since the acquisition, the good faith discussions between Patrice and Ubisoft aimed at aligning Patrice’s and the studio’s visions have been inconclusive. As a result, Patrice has left the studio." Their statement from the designer takes a slightly less diplomatic tone:

Contrary to any statements made earlier today, this morning I was terminated by Ubisoft. I was notified of this termination in person, handed a termination notice and was unceremoniously escorted out of the building by two guards without being able to say goodbye to my team or collect my personal belongings.

This was not my decision.

Ubisoft’s actions are baseless and without merit. I intend to fight Ubisoft vigorously for my rights, for my team and for my game.
