For altruistic survivors working together to see another day.

The Begrimed Chain will stack multiple times on the same survivor if they are hit multiple times by the chainsaw without being healed. The effect are as follows:

7 begrimed hits = no generator repair speed

8 + begrimed hits = negative progress towards generator repair speed.*

* Yes, you can un-repair a generator apparently. You can can the effects multiple times on a person on a hook.
