Safe and Sound

Safe and Sound is an optional mission in Borderlands 2 to find Marcus's safe in Caustic Caverns.

Objectives

 * Find Safe
 * Kill 25 Sanctuary squatters
 * Bring pictures to either Marcus or Moxxi

Strategy
After you find the safe in the Caustic Caverns, you will encounter a mini-boss - a giant crystalisk named Blue. Kill him just like any other crystalisk by shooting the crystals on his legs. He is pretty easy to kill. After killing Blue and opening the safe, you'll find lewd pictures of Moxxi. You will receive a call from both Marcus and Moxxi asking for the pictures. If you take them to Marcus, you will be rewarded with a relic; if you take them to Moxxi, you will receive a shotgun.
