Wow, what a waste of time. I fell asleep for 30 minutes halfway through and had apparently missed nothing - the main character, a total jerk, was still stuck in the elevator, yapping on the phone and intercom. Random people and zombies die when they stick their head through the half-open elevator doors. Nothing else seems to happen. More blabbing on the phone, more random zombies bashed in the head... booooooring.
