Highlands Outwash

Speak with Sir Hammerlock about exacting revenge on Old Slappy. Take Sir Hammerlock’s artificial limb (of a gentleman), and Fast Travel to Highlands Outwash. There’s a massive thresher that lives in the shallow reservoir surrounding the Hyperion Extraction Plant, and the only way to lure it out of hiding is with Sir Hammerlock’s scent. Take a minute or two to eliminate any Loaders you encounter at the Hyperion Extraction Plant—you don’t want them shooting at you while you’re fighting Old Slappy—then leap into the water and wade out to the post where you can affix the arm.

Tie Sir Hammerlock’s artificial arm to the post in the water at Hyperion Extraction Plant.

Old Slappy is a massive multi-tentacled thresher that isn’t very mobile but boasts tremendous range and can lash out at you from considerable distance. Open fire on its head, and try to focus your bullets at its large blue eyeballs. Circle-strafe around Old Slappy to avoid its tentacles while continuing to fire on its eyes. Old Slappy doesn’t have a shield, so there’s no need to worry about using Shock weapons. Instead, go straight for Fire or Explosive, and bombard it with every attack you possess, including your Action Skills. Maya’s Phaselock ability inflicts instant damage—Old Slappy is too large to lift out of the water—but it’s still worth using the attack. Reload on the run, and continue aiming at its eyes until you’ve defeated the beast.

Retrieve the arm and collect the spoils—Old Slappy is prone to dropping good loot. The quickest way back is via the Fast Travel station in The Highlands. Continue through the Orbital Receiving & Processing area of Highlands Outwash, and drive to Overlook once back in The Highlands.
