OS: Windows® XP, Windows Vista®, Windows® 7 (only).The Na'vi can also traverse treetops and are more versed in stealth combat than the Human marines. The Na'vi gameplay also includes the ability to ride various animals native to the planet of Pandora. This character also gains experience, but it's unknown if it's shared between the two player characters. The Na'vi character is melee-based with a number of weapons at hand but he can also use the animals against the enemy soldiers. The game also includes a character progression system with the player gaining experience points after every kill to gain levels. These abilities range from cloaking to calling down carpet bombing or artillery strikes. The abilities are mapped to the face buttons of the controller with an individual cooldown for every ability after use. Each side has access to unique weapons and abilities, and the Humans have access to a variety of vehicles, while the Na'vi use tamed animals for much the same gameplay reasons. The game is a third-person shooter, with the player being able to play both as a Human and as a Na'vi. The game is set two years before the movie, so the story that will not spoil the film. The native inhabitants of the planet called the Na'vi are not too keen to the idea of Humans taking away their land for the treasures and resources that lie below. Humans have found the planet and are using it for personal gain. Pandora is a habitable moon to a gas giant.
