Starting the Quarry Rescue Quest
Travel to the Aburrey Quarry, situated southeast of the Hub area.

Entering the Quarry
Follow the designated path until enemies are encountered. After defeating them, search for an opening that features a rope for descent.



Descending into the Quarry
Utilize the rope to slide down into the quarry.


Continuing Through the Quarry
Advance along the path until a gate with two pressure plates is reached.

Opening the Quarry Door
To open the door, two double containers must be placed on each of the two pressure plates.


First, move the accessible container in front of the container on the right. Enter the container and proceed around the corner to activate a forklift, which will raise a box, creating a path to walk across.


Jump onto the crates, then move to the opening behind the electric fence. Here, two more movable containers and another pressure plate will be found. Place the small crate on this plate to deactivate the electricity. Move one double crate to the central pressure plate. Retrieve the other double crate previously used for climbing and place it on the remaining pressure plate.


Reaching the Sender’s Location
Follow the path to an elevator. Upon ascending, Ramon will be encountered, marking the completion of this quest. This event transitions directly into the quest Fix The Super Crane.
