About this video

I have reached the complex containing the Brain Scorcher. 
I can hear strange noises and i have vodka vision. 
After turning off the Brain Scorcher, hell brakes loose. 
The fanatic cultists flooding the complex. I fight for my life.
 My ammunition depleted , i have to get creative to fight off the Monolith.
 Finally i reach the exit and vanish into the night.
