Layout and hazards
The Vault resembles a giant abandoned underground factory, with rusted steel beams and platforms as far as the eye can see. Various machines resembling generators are dotted throughout the area which explode into an area of freezing vapour or fire upon destruction, depending on the gas emanating from their spout. Beneath the rusted metals you'll find compositions of Vault Rock, a hardier version of normal rock that is tough to dig through. Pools and vats of toxic sludge are common, with no naturally occurring water to purify it with. Explosive crates, propane tanks, toxic sludge barrels and oil barrels make a return. Large acid containers, both on the ground and hanging from the ceiling, make an appearance here. Occasionally, the path will be blocked by small pipes, but these can be dug through fairly easily.
Points of Interest
- A giant vat of acid can often be found here. It is encased in glass, hinting that glass is the only material that doesn't corrode from exposure to acid. It can be easily broken just like ice, and if this is done then the contents will leak out, destroying much terrain (and possibly some enemies).
- One of the Fungal Altars can be found here around the center of the biome, right before the entrance to the next Holy Mountain.
- A large brain looking object can spawn here, destroying it will often reveal either a Max Health Upgrade or Treasure Chest inside.
