James Cameron's Avatar: The Game is a 2009 third-person action video game prequel to James Cameron's Avatar. The game was developed by Ubisoft Montreal.

Although James Cameron's Avatar: The Game is named after the movie, the story itself doesn't follow the plot of the film. Instead the player takes on the role of Lance Corporal Ryder, a signal-specialist who is send to the distant moon Pandora. But Ryder isn't just any other soldier. Instead he or she is one of the selected group of people that take part in the so-called Avatar-program. Avatars are a hybrid of Na'vi DNA and human DNA that have been created in order to better interact with the inhabitants of the planet: the Na'vi, tribe-like and technology-wise not very advanced people that are one with nature. Although the Na'vi are friendly to the new-comers at first, soon the humans want more than just diplomatic relations. They want to relocate the Na'vi in order to be able to strip the planet of its natural resources. A war breaks out which only one side can win - it is up to the player which it will be.
