Brutal Legend is getting a lot of attention at this year's E3, but if Activision has its way the game will never be released under EA. The Associated Press reports that the company has announced that they are suing to stop the release of the game. Activision Entertainment Holdings has opened a suit against Double Fine Productions, claiming the developer transferred rights to Electronic Arts. Activision claims they still hold a valid contract to release the game. They say they've invested about $15 million into it, and clearly want to make that money back.
