The game will take you into the heart of Pandora, an alien planet that is "beyond imagination" says the PR.
Here's the official line:
Gamers will encounter the Na'vi, Pandora's indigenous people and discover other life forms the likes of which have never been seen in the world of video games before. When conflict erupts between the RDA Corporation, a space-faring consortium in search of valuable resources, and the Na'vi, gamers will find themselves thrust into a fight for the heart of a planet and the fate of a civilization.
