A lot of mobile game announcements were made at the Game Developers Conference (GDC) in San Francisco this week. Among them: Glu Mobile said it signed a multi-year agreement with Fox Mobile Entertainment to develop and publish mobile games and content based on the ICE AGE brand. Glu will begin by developing and publishing the mobile-exclusive game ICE AGE: Mammoth Mayhem, scheduled for launch this summer.

Another game, based on Fox's ICE AGE 3 movie, is scheduled for release in 2009. The movie is due to come out as a theatrical release in July 2009.

The franchise apparently has been a successful one for Glu. ICE AGE 2: Arctic Slide was one of Glu's top-selling games worldwide for 2006. The company says the game's global marketing campaign rallied support from wireless operators in key new markets.

Glu Mobile also unveiled its roadmap of upcoming titles launching in North America in the first half of 2008. The additions to its portfolio include titles based on global brands from partners such as Microsoft and Warner Bros. Digital Distribution, casual titles from PlayFirst and Big Fish Games, as well as Glu original titles.
