Intruder

The Intruder is an enemy in Marrow.

Description
The Intruder appears in several long hallways in Marrow. It will continuously walk back and forth across the room, fading in and out of existence as it does. When it is completely faded, it cannot be attacked, but cannot damage the player either. When The Intruder is killed, it will melt into a puddle before reforming some seconds later where it will continue to patrol the room
