"Mirror's Edge" is an action-adventure platform game where the player must control the protagonist, Faith Connors, from a first-person perspective and navigate a city. To progress through the game and its storyline, the player needs to complete a series of levels that involve performing a linear sequence of acrobatic manoeuvres. These include jumping between rooftops, running across walls, climbing pipes, walking along ledges, sliding down zip lines, and getting past opponents controlled by the game's artificial intelligence. Faith's arms, legs, and torso are prominent and their visibility is used to convey her movement and interactions with the environment. Her momentum is an important aspect of the gameplay, as preserving it through multiple obstacles allows the player to run faster, jump farther and climb higher. To help players chain moves seamlessly, the game employs a navigation system, called Runner Vision, which turns certain objects in a bold red color as Faith approaches them, allowing the player to instantly recognize paths and escape routes.
