"Head to Hyperion Mortar" is an objective in the sidequest This Is Only a Test in Borderlands 2
Walkthrough[edit]
Time to head for Aggregate Acquisition. Head through the tunnel to the South, go to the left and head into the Hyperion Base. You need to head to the North. Once again, you need to fight on through. There are plenty of Loaders and a few Combat Engineers. Once at the Northern end, go on up the stairs and turn to the left. You will find the controls you need just ahead of you.
