In UVHM especially, getting the turrets to kill the enemies for the constructor bot is quite tedious, especially when the psychos are always hitting you and knocking you around. Well there’s actually a “safe spot” of sorts that makes you invisible to the psychos, and leaves them standing around to get hit by the turrets.
-On the left side of the room, go underneath the staircase.
-Line up with the center line under the staircase
-Walk under until you’ve snugged in
All you have to do is wait for the turrets to kill the psychos, without them even knowing you’re there. You can even throw some grenades or any other method to hit them around corners, they still won’t be able to hit you even if they look at you. This speeds up the process a bit, considering the turrets do hardly any damage it seems.
