S-10 is currently an unreleased entity planned to roam Section S, being a doppelganger of A-10. It is the first entity players will encounter upon arriving to the section, and as it name implies, it will make its debut at room S-010. It was initially scrapped due to Interminable Rooms being momentarily canceled, however with the continuation of the game, the entity may have a chance to be added into the game in a later update.
S-10 would act like the entity it is a doppelganger of, rushing to the current room and de-spawning once reaching the closed door.
Due to the entity not being added yet, its mechanic is subject to change and could possibly differ greatly from the original mechanic or simply remain the same.
