Achievements are game-defined goals that are stored and displayed in your profile. Achievements can be as simple, complex, or off-the-wall as a game wants.

Your achievements include all of your awards, medals, and high scores.

Achievements are a feature of every Xbox 360 game you play, giving you something to crow about while showing other Xbox LIVE gamers the titles you excel at and comparing your achievements to other gamers who play the same titles you do.
