Lasers is an Interactive floor where players must survive Dr. Doofenshmirtz's Laser. I wonder if he used the laserinator?
This floor appears to be a big stone platform with Heinz Doofenshmirtz at the end. After a short wait, Doofenshmirtz starts attacking with lasers. The higher the elevator is, the more difficult this floor becomes - from easy to extremely difficult. The difficulty ranges from 1 to 8. There are some victors of the highest difficulty, but most were from testing and some were even fraud attempts since there were exploiters who likely got the badge. As of seeing a legitimate completion, G_XAR is known to be the only legitimate victor.
Fun Fact: The old laser floor was removed due to hardcore lag.
