There’s only one vault symbol in this area. When you first enter Jack’s Office, there are two sets of desks on either side. Go to the northernmost row of desk on the eastern side and you should see a small vault symbol on the ground between the last desk and the plant.
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.
