Performing the Damage Generator Action on a Generator triggers Nowhere to Hide:

The Auras of all Survivors within 24 meters of your position are revealed to you for 3/4/5 seconds.

For each Survivor you hook for the first time, No Way Out gains 1 Token.
Once the Exit Gates have been powered, No Way Out activates:

When a Survivor interacts with an Exit Gate Switch, you receive a Loud Noise Notification and The Entity blocks both Exit Gate Switches for 12 seconds and an additional 6/9/12 seconds per Token in your possession, up to a combined maximum of 36/48/60 seconds.

Injuring a Survivor will call upon The Entity to block pallets from being pulled down within a 32 meter radius of the Survivor location for 15 seconds.

The Hex effects persist as long as the related Hex Totem is standing.

Each injured, dying, or hooked Survivor afflicts Survivors with a stack-able 1/1.5/2 percent Action Speed penalty to Repairing, Sabotaging, and Cleansing, up to a maximum of 4/6/8 percent.
Increases the Action Speed penalty by a further 12 percent, if there are 4 Survivors, who are either injured, dying, or hooked at the same time.

Instead of snuffing Boon Totems you destroy them.
Destroying a Boon Totem this way reveals the Auras of all Survivors that were within its range at that moment for 6/7/8 seconds.

After a generator is repaired, The Entity blocked the generator with the most progress for 30 seconds.  You see its white aura during this time.
