"While you'll have many missions to complete, how you go about it might vary from player to player. In one memorable scene early on in the game, you're being chased by police in a building, with bullets whizzing past your ears, and you must frantically climb the staircase and find a hiding spot behind boxes. Or you can climb up onto a shelf and find an opening to an air vent to crawl through. Or you can kick open a door to the roof, hop over an electric fence and run like mad. While you're encouraged not to use weapons in the game (in fact, you can unlock a special Xbox 360 Achievement or PlayStation 3 Trophy for not firing them) it is possible to pick up and fire a gun, if you like. Otherwise, our heroine can punch or kick to confront baddies (and disarm them by pressing "Y" on the Xbox 360 controller).
Along with the main campaign is a special Race mode, where you're dropped back into the city and can compete against other Mirror's Edge players to see who has the best time; every move throughout the obstacle courses is recorded and your time trials appear as red silhouettes of your character for others to beat. There are a few minor issues, such as some moves are hard to pull off (such as hopping between two walls) and the first-person view can make it tough to know when to jump from one building to another, but overall, Mirror's Edge is a fantastic first-person adventure worth every dime.
