Any generator within a range of 128 meters that is being repaired by two or more Survivors is marked by a yellow aura.  When the generator is first highlighted, Discordance triggers a loud noise notification on the generator.  After the generator is no longer within range or is no longer being repaired by two or more Survivors, the aura remains for another 4 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.

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.

While carrying a Survivor, increase your Carrying Movement speed by 6/12/18percent.  Increases your Terror Radius by 12 meters.
