While you can kill people in the game, it's very possible to complete it without hurting anyone, and you're encouraged not to. There's even an achievement for not killing anyone.
Ranked in these QuestionsQuestion Ranking
Pro Innovative, parkour-inspired, first-person platforming with excellent sense of motion
The game's core mechanic is about traversing levels using wall-jumps, rolls and slides without losing momentum. It does a great job of creating a fluid sense of motion that you have complete control over.
Pro Unique, minimalistic art-style
Mirror's Edge is set in a world where a totalitarian government runs a city and tries to eliminate anything that stands out, such as the free-running protagonist. The levels are created minimalistic, mostly white with aggressively contrasting primary colors, to represent the oppressive nature and sterility of the world.
Pro Great soundtrack
The soundtrack's spacious ambient texture coupled with electronic beats and synthetic sounds supplement the game's otherworldly, contrasting setting. The complete soundtrack is available with the purchase of the game.
Pro Keyboard controls work quite well
Surprisingly (for an EA game especially) the keyboard controls are actually designed to work quite well.
Pro Time trials
There are time trial bonus levels that are free of platforming sections and combat, just pure timed running missions.
Con Poor combat sytem
The combat system often feels out of place and definitely interferes with the flow of the gameplay.
Con Some people may experience motion sickness
In order to maintain its immersive nature, Mirrors Edge has virtually no UI, other than a small dot at the center of the screen. This should ward off motion sickness for most people, but be aware that if you're queasy, you might not feel too well after playing.
