The content sends players to Wam Bam Island to partake in the largest Headhunter DLC mission released, according to a 2K blog post. "At the end of your adventure, you will battle a foe that may look familiar – Crawmerax Jr., the son of the great crab worm from The Secret Armory of General Knoxx add-on from the original Borderlands."
The content now shelves the Borderlands sequel, giving developer Gearbox ample time to focus its efforts on the next installment of the game: Borderlands: The Pre-Sequel.
Successfully completing the Headhunter 5: Sir Hammerlock Versus the Son of the Crawmerax DLC (boy, that's a mouthful) will allow players to wear a shrunken version of the final enemy's head like a hat. If swanky travel duds are more of an incentive, each character will net a beach-themed skin as part of the content. Taking on Handsome Jack in an "Aloha shirt"? Say no more.
