Our story starts with Gabe Newell. He was on his way to the room with the button that releases the 100th wrench, and the update. However, he got stuck in the door way, and required a team of 50 people to push him out. When he got pushed out, he fell. But the force of the fall made him break the floor, causing him to fall 10 stories down. Now there is a giant hole in the floor and they can't get to the button.
