SCP-035 (a.k.a. Possessive Mask) is an unknown entity in BIWx3. It's unknown if it is in the current version of the game, or if it was added to the game prior to the game's corruption. However, it can be found in the game files.
SCP-035 is based off the official SCP entry of the same name.
It is a white mask, somewhat resembling a traditional "comedy" mask. However, it has black lines protruding from its eye holes and the sides of its mouth, intended to represent "tears".
Again, this entity hasn't been encountered in-game, so it's unknown what it actually does. Based on the original SCP's behavior, it's possible that it could lure the player to putting it on, and/or emit dangerous acid.
- In the game's files, this entity is often misspelled as "SCP-036", even though SCP-036 is an entirely different entity.
