Where the Cauldron South Subwayne puzzle appears
During the Joker Cards mission, you will eventually reach an area containing a large movable container. The puzzle is located directly beside the Subwayne shutter hidden in Cauldron South. The area is fairly compact, but several interactive objects are blended into the environment, making the solution easy to overlook on a first playthrough.
The Batmobile is essential here because standard character abilities cannot move the container blocking access to the mechanism behind it.
How to unlock the Subwayne in Cauldron South
Step #1
Drive your Batmobile to the large container during the Joker Cards mission. Look for the vehicle interaction point attached to the container.
Use the Batmobile pull function to drag the container out of the way. Once moved, the hidden section behind it becomes accessible.
Step #2
After removing the container, walk behind the newly opened area and locate the loose lever piece hidden there.
Pick up the lever and carry it toward the nearby lift mechanism.
Step #3
Place the lever onto the lift device to repair and activate the mechanism.
This starts the pressure-based puzzle connected to the Subwayne shutter system.
Step #4
Before attempting the puzzle, make sure to summon your companion character. Both characters are needed to properly activate the pressure setup.
If your companion is not nearby, the puzzle will not register correctly.
Step #5
Ride your Batmobile toward the lift area and position it on the required pressure section while your companion helps maintain the activation state.
Once the correct pressure combination is achieved, the mechanism activates automatically.
Step #6
After the puzzle completes, the Subwayne shutter in Cauldron South opens permanently.
You can now use this Subwayne station for fast travel and easier navigation through Gotham.
