How to get under the map in "Three Horns Divide" on Borderlands 2. ----------------- Text Tutorial: Navigate to "Three Horns Divide", and travel to the Northeast corner (near the entrance the Sanctuary. Go toward the "Catch-a-ride" station, and turn towards the cliffside/edge of the map. (To the left, if facing the front of the Vehicle station) Jump onto the ledge bordering the cliffside, and drop down (while hugging the wall). If you travel too far off the ledge, or fall off of the lower area, you will die. Once here, face the wall, and run along it to the left. You will reach a small crevice with an opening at the back corner. Crouch, and walk through this opening. You will now be under the map in a small area. **NOTE: The area under the map is quite small, and traveling to the extreme edge on either side, or falling below will cause you to die.
