Assassin's Creed creator Patrice Désilets is back at Ubisoft, the company has confirmed.

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.

"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.

Ubisoft purchased THQ Montreal during the THQ auction earlier this year, in a transaction that included 1666, an unannounced project helmed by Désilets.
