Windows 7: looking for the name of this game

i remember i played a game for like 5 or 10 minutes a loong time ago, and its weird how these irrelevant little memories can totally just rip you apart when trying to remember details! i want to find the name of this game, i am 100% sure that i know it, but i just cant remember it! so heres what i remember.
at some point in the game you are running away from people who have guns and are shooting at you in a building with stairs, glass, its white-ish, sorta like an expensive office building or something. you can go outside too, and while youre running you can jump and hang onto pipes and stuff. the pipes are orange if i remember correctly, and theyre supposed to show you the way out by jumping towards them or taking the items or stuff. i dont remember most of the details because it was only for like 10 minutes, and could have been a demo for all i know. id really appreciate it if anyone could name this game (or a game that might sound similar, cause you might be right) thanks

Is it Mirror's Edge? How long ago did you play it? Mirror's Edge came out in 2007. Mirror's Edge - Wikipedia, the free encyclopedia
