Hey all, I seem to be missing something to deactivate the lasers on the upper floor of the synth building. I know about the locked door on the roof or whatever, but I cannot seem to find the key either?

Can't remember where is what, but you may have missed some key on the floor.
Purple laser door is deactivated by interacting with the electrical box (in the vents i think? wich you can get into through the cell rooms)
