They can interact with 173, 106, and 049 in the game

However, you cant escape the facility completely, the facility can be nuked, unless you destroy the warheads, you can try to go back, and die from a nearby helicopter, should you choose to detonate nukes or they arent used in Gate B even if on, or remain in the final room, have the warheads detonate...

Its not the 9Tail Foxes that kill you, its MTF Cloud 9 that does, and if you choose to run from that task force or the warheads dont go off even if they are on, you can die anyway from the apache, but the door before the one with the combination pad is locked, thus trapping you

This hints at a way SCP-106 can appear near SCP-914

SCP-990 actually can talk to you while you load in and you see his screen

It's a good thing that little bug is over, you usually are in the section of the building the SCP-106 containment area is in when you escape

We still need to try hard, as that guy never gives up easy, he can pull you in even if god mode is on
