By community demand, Tripwire Interactive would like to announce the creation and use of the "Greylist". This is a list, much like the whitelist that allows the use of your perks, however with this list your perks will be reset to what they were at the start of the round when the map changes. This was created so community members could use their hard earned perks with their favorite mods and mutators!
The current list can be found HERE
