Secret Ending?

#1
So I was wondering around the SCP:CB SFX folder and I found a file called "EndingB1.ogg". I was curious as there were only 2 Gate B endings(there were 3 files) so I booted SCP:CB up and tried to get the ending. The file made me confused as I tried to get the ending no matter what but it is impossible. It mentioned about dying in front of the elevator but what does that mean? It also said that D-9341 died thanks to 173. Can you tell me how to achieve this ending?
