Perk Idea Hex:Lock
Whenever the Generators are powered or 3 survivors have been killed a dull totem on the map becomes active. The Hatch remains locked until the totem is broken and 30/45/60 second increase to open the escape gates.
EDIT: The last survivor gets 60/55/50 increased action speed for repairing, healing, and cleansing while the totem is active.
EDIT: The Killer's aura reading abilities are negated on activation.
