This game is based on the combat experiences of a fictional character, a cyber-soldier, and his Artificial Intelligence (AI) sidekick. Halo is classified as a first person shooter type game. An FPS or first person shooter game is a type of game which allows its player to perform as if they are the main character. Since the original game was developed for computers, a keyboard was used to control motions and actions of the character and surroundings. On the Xbox game, traditional controls are used where the left thumbstick on the controller moves the character and the right thumbstick changes the vantage point. The right trigger is set to fire weapons, while the left trigger throws grenades at enemies and opponents.http://www.machinima.com/article/view&id=464
