Game engine company Trinigy said Tuesday that game development house Zed Group will use the Trinigy Vision Engine to develop an online PC game based on the upcoming Sony Pictures CG animated film, Planet 51. The film, in which humans are the "aliens" invading a planet inhabited by green beings, is slated to release this November, alongside the release of Zed's Trinigy-powered online PC game and console versions of Planet 51. Zed's director of product innovation Christopher Head said in a statement that Zed has worked with Trinigy for "many years on a wide range of projects." Trinigy said the Vision Engine will help "accelerate development" of Planet 51's online game world. Zed Group's sister company is Madrid, Spain-based Ilion Animation Studios, which is producing the movie Planet 51. Ilion was formed by founders of video game developer Pyro Studios, developers of the Commando series of games. Sega and Pyro announced a video game publishing deal for Planet 51 console games in February this year. Planet 51 is also in development for Xbox 360, PlayStation 3, Wii, and DS.
