Ok, just read through 27 pages of this thread to see if anyone else noticed this on my wife's behalf. When the helo is being fired up and
Burt is getting ready to defend the landing pad, you can hear a "ding" in the background. Then Burt shouts, "They're coming!" as you hear the zombie horde coming through.
Is it just us, or did the zombies take the elevator up to the roof???
If they did, my wife wants to know what did the zombies do, wait patiently for the elevator to arrive on their floor, slowly walk in, listen to some muzak, and then spring to undead life when they saw Burt and company?
