SCP-1499 is a Soviet GP-5 gas mask. A seal test performed on the object suggests that the object retains its original functionality. The anomalous effects of SCP-1499 activate when a human places SCP-1499 on their head. Approximately one second after SCP-1499 is fully secured on the subject's head, the subject vanishes from view, and is no longer detectable. The subject reports no feeling of motion at this time. Testing has revealed that two-way radios remain capable of both receiving and transmitting despite the subject being undetectable. Upon wearing SCP-1499, test subjects report completely different surroundings than they were in prior to wearing SCP-1499. Subjects have reported that it appears barren and inhospitable, with tall black towers filling the area. Subjects have also sighted entities in this landscape.
SCP-1499 can be found in the Light Containment Zone, in the two door hallway which requires level 3 keycards to access. It can be found in the same side as the room with the safe which does not contain SCP-500. When worn, the player is transported into a dimension containing many entities designated SCP-1499-1.
Approaching a stationary instance of SCP-1499-1 will cause all instances of SCP-1499-1 within the dimension to become hostile and attack the player, though approaching an instance of SCP-1499-1 while it is walking will cause it to walk directly away from the player. Any injuries sustained in this dimension are transported to the real world, as-well.
The player must be wary which when SCP-1499 is about to be worn, a few seconds delay will occur before its effect takes place; in this small amount of time the player will be still vulnerable to immediate threats.
Upon wearing SCP-1499, the player will always spawn in the nearby of stationary instances of SCP-1499-1, which will attack the player, whenever he will inadvertently approach to them:
It's highly suggested to locate as soon as possible the most clear way from any stationary SCP-1499-1 instances and draft off, as choosing the wrong direction may lead to inadvertently trigger the instances and force the player to remove SCP-1499.
When put through SCP-914 on coarse or rough and put an item it will get destroyed (not all the items),in 1:1 it will give you something similar to the item you put in SCP-914, then on Fine or Very Fine it will turn items to "Fine" items.
Appears to be a stuffed bear shaped from what is believed to be human ears. May be found in some hallways and screams at the player if approached. The scream causes ears to grow all over the player and in the lungs which results in death after a few seconds.
