The exact solution to this Act 4 puzzle.
The first mechanism is located on your way to the first maze, so it can’t be missed.
You eventually find yourself inside the main structure of Act 4, with multiple paths to explore.
Be careful, as there are lots of enemies ahead.
You’ve now got a shortcut back to the entrance of the structure.
There’s one of the large enemies ahead.
Either give it the run around or use your shotgun-like weapon to kill it.
You’ll find the third and final rig needed to blast a hole in the creature ahead.
Activate it, then run back to the lift, as there’s two large enemies in this area.
This third hole and maze islocated just behind the lift in front of the shortcut you created.
