Go to the large room just before you fight the boss, which is just south of where the robot’s legs are attached. Facing away from the doorway that leads to the latter room, go down the stairs and into the first east passage you come across, where you’ll find the symbol on the southern wall, at the end.
Taking place between the events of Borderlands 1 and Borderlands 2, The Pre-Sequel details the events of how Handsome Jack became what he was during the second game. You play as one of four new character classes as you explore the moon of Pandora, Elpis, jumping around in low gravity, collecting all new loot and just shooting everything and anything you find!
Inside you will find:
A complete walkthrough of all main story missions and all of the optional missions;
A guide to complete all of the location-based Challenges;
How to get every single Achievement and Trophy;
Maps, images and locations of all of the Vault Symbols.
