Assassin's Creed creator and designer Patrice Désilets says he has been fired from Ubisoft fewer than two months after he rejoined the company.

Speaking with Polygon, Désilets said although Ubisoft told the press that he had left the studio after "good faith discussions", his employment was actually terminated – something he intended to fight.

"Contrary to any statements made earlier today, this morning I was terminated by Ubisoft," he said.

"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."

Earlier today, Ubisoft officials implied that the parting had been amicable.

"The acquisition of THQ Montréal in January allowed Ubisoft to welcome 170 experienced developers, including Patrice Désilets, to our existing and renowned workforce," said an Ubisoft spokesperson.

"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. Our priorities remain with the teams already hard at work on projects in development. They are at the root of Ubisoft Montréal's past and future successes."

Désilets left Ubisoft for THQ Montreal in 2010, having played a big role in the development of some of its key franchises including Prince of Persia and Assassin’s Creed.

At the time, rumours swirled that the reason for his departure was a poor relationship with Ubisoft president Yannis Mallat.

In January, Mallat claimed that he had great respect for Désilets, and that the celebrated game designer would be back.

Désilets served as a creative director at THQ until its bankruptcy earlier this year, at which time he did indeed return to the French developer and publisher.

"We are very pleased to welcome Patrice to Ubisoft again and anticipate that this renewed partnership will produce new ideas and high-quality titles for Ubisoft's customers," said an Ubisoft spokesperson at the time.

Ubisoft purchased THQ Montreal during the THQ auction earlier this year, in a transaction that included unannounced projects helmed by Désilets codenamed Underdog and 1666.
