Ok. After recently reading the zombie survival guide again, I was informed that one in four "infectees" can climb a ladder. So I had to change my plan a little bit...
So here is a terrible drawing I threw together on Paint. For the time being, lets assume
Blue Line = Staircases
Green Line = Elevator route
Green blob thing (?) = Elevator Car
Purple Dots = Survivors
Red Dots = Infected
Red Lines = Infected Routes
