Description

The Entity Response Corps (ERC) Is dedicated to exterminating all hostile entities that live throughout the backrooms. Members consist of those who have seen the horrors of the backrooms, and want to work towards making it safer through extermination. We are willing to accept help from other survivors and groups attempting to aid our goal, but we will not tolerate those attempting to interfere with our efforts.
