During an Incursion on Warehouse map > Liberty Island > New York, I found for the first time ever a Lurker in one spot doing this.
The Lurker was fixed to this spot legs walking but not moving head aimed up. I got an in game notice it sensed me but no howl or reaction especially since it could not move and the head was always aimed up.
Not a normal pose for any of the enemies.
