Steam's daily deal for Saturday is Mirror's Edge.
Metacritic score: 81
"In a city where information is heavily monitored, agile couriers called Runners transport sensitive data away from prying eyes. In this seemingly utopian paradise, a crime has been committed, your sister has been framed and now you are being hunted. You are a Runner called Faith — and this innovative first-person action-adventure is your story.
Mirror's Edge™ delivers you straight into the shoes of this unique heroine as she traverses the vertigo-inducing cityscape, engaging in intense combat and fast paced chases. With a never before seen sense of movement and perspective, you will be drawn into Faith's world. A world that is visceral, immediate, and very dangerous.
Live or die? Soar or plummet? One thing is certain, in this city you will learn how to run. From the makers of the groundbreaking Battlefield franchise, Mirror's Edge is an action-adventure experience unlike any other."
