"In Levels 3 & 4 of Elevator Action, WashYourFace figured out that if you sit in a safe spot (far side of a wall) and wait out the enemies as they go more and more nuts trying to shoot you, the aggression counter will eventually roll over and they'll be as meek as kittens for a few minutes. Without that, Level 4 is a brutal, cheap nightmare."
Found this from last year. I'm glad somebody remembered, because I almost forgot myself, and not sure if the NA archive would still have it. I'm writing it down this time (I guess so I can beat Elevator Action years from now).
