Passing door 70, you made it to the Heavy Containment section. This was arguably the best part of the Blacksite to be in, since there were a lot of hiding spots from Anglers and Pandemonium: side rooms, lockers, etc. While searching for loose assets in the drawers, the lights dim and turn red, and all the lockers and drawers start opening and closing randomly. Usually this was a sign of the entity Harbinger coming your way, but... You're not in an endless run..? Then, you realized that one of the expendables that died were probably messing around with you as a ghost. This was called 'Post-Mortem Haunting', and the ghost could either help alive expendables, or just be a downright menace. Let's hope they're actually here to help you.. The batteries in your flashlight recharge suddenly. Huh. Maybe they are here to help you.
