Lost Cave is a subterranean area in Borderlands, located in the centre of The Arid Badlands and location of the Shock Crystal Harvest mission. The other main highlight of the area is a Claptrap in the middle of the cave system, offering a mission to save him.


The Cave consists of mostly skags, a few larva crab worms and two bandit outposts. The first encounter will be with four larva crabs. Then, there will be a fork in the road. The left branch heads deeper into the cave system and fight some more crabs, while the right will be a fight with a group of Alpha Skags. Due to lack of corrosive or powerful equipment early in the Borderlands campaign, it might be ignored, but there is a safespot that will aid in combat.

Deeper into the cave are a few more larva crab worms. Beyond them, and to the right is a red chest and a save point. To the left is a basic skag den, possibly containing alpha elemental skags. Further ahead a medium-sized bandit outpost hides a red chest down a left branch.

Another regular skag den is on the way to the final bandit outpost, proceeding deeper leads to a large cavern that is full of regular Alpha Skags. There are two red chests at the end of this cavern.
