Safe and Sound

Safe and Sound

This is available at Chapter 11: Wildlife Preservation. Talk to Marcus to start this mission.

Fast-travel to the Sanctuary Hole in the Three-Horns Divide. Head back to where the Sanctuary once was located, then clear the area of enemies. Make your way to the northeast corner of the map to find a lift. Ride it down and continue killing enemies there. Go upstairs and exit to the southeast to find another lift going down. There should be another lift there leading to the Caustic Caverns. This is the same are as Sir Hammerlock's Perfectly Peaceful mission.

Follow the straight path until you reach the Rumbling Shore. There are some shallow grounds you can hop on to reach the other side of the Oozing Discharge. Follow the marker to find the safe on top of some blue crystals. Approach it and a large crystalisk called Blue will appear. Don't be intimidated by it as it can be defeated as easily as you can dispatch a normal crystalisk. Aim for the crystals to deal critical damage. Once done, open the safe and you'll have the option to deliver the pictures to Moxxii or Marcus when you get back to Sanctuary.
