This is a easy and effective way to do the powerup Easter egg with just two people.
Credit goes to : Bdm niigrrb3atr(me) and srathert20 (Stephen)

Step1:open up doors to power room and to at least one other lander besides the starting one

Step2:after you turn on power have one person do the method that was used to do the lunar lander glitch meaning lay down right where the bump is on the lunar lander you should lay down at the point where the star is at the bottom of the lander when it is coming down in position.

Step3: have a friend call the lander to a different position,when he does this you should be outside of the rails of the lunar while it is lifting you in the air and as it does this it will kill the down the player on the lander and almost kill him instantly

Step4: the player who died should hear laughter like when you hit a Teddy bear on the box then shortly after the player still alive will hear it to once heard have the player end the round by killing the remaining zombies

Step5: have fun get kills and watch the powerups come at a crazy rate
