You know that the best way to stay one step ahead is to keep tabs on the competition.
Wiretap activates after completing a total of 50% worth of repair progress on generators.
When standing next to a generator, press the Active Ability button 1 to install a Wiretap, which stays active for 100/110/120 seconds.
Affected generators will be revealed to all Survivors by a yellow aura. Only one Wiretap can be active on a generator.
When the Killer enters within 14 meters of the generator, their aura is revealed to all Survivors.
Wiretap deactivates when the generator is damaged by the Killer or when the timer expires.
