Activision Inc. on Wednesday said it acquired Quebec-based game developer Beenox Inc. in a move to boost its presence in Canada. Terms of the deal were not released.

Closely held Beenox will become a wholly owned subsidiary of the Santa Monica-based videogame publisher and Beenox’s management team and key employees signed long-term employment contracts with Activision, the company said. Beenox’s 32-person team will continue to be based in Canada.

Activision has worked with Beenox since 2003 on a number of popular titles, including “Shrek 2” and “Tony Hawk’s Underground 2,” as well as on the game adaptation of the upcoming film “Fantastic Four.”

This marks the third acquisition by Activision this year. Activision bought Novato-based Toys for Bob in early May and Vicarious Visions of Troy, N.Y., in mid-January.
