Bloodborne Cave

 is located east of the Brotherhood of Steel Safehouse and northwest of Bitter Springs. A large number of Night stalkers and a Legendary night stalker reside in the cave, it consists of a single interior section.

Bloodborne cave
Inside, there is a campfire near the entrance (left path, requires jumping down or clearing the cave) on which the player can find a worn key. This key opens a Hard-locked gate farther along on the North side of the cave. Beyond that gate lies a significant amount of loot. However be very careful because right beyond the door is a tripwire which triggers a Grenade Bouquet that is deadly as it is exactly behind the player and in an enclosed space. Either disarm the tripwire or jump over it to avoid triggering it.

Notable loot
ammo (depending on the gun found) can also be found next to a dead body, located near the Legendary Nightstalker

 * A 12.7mm SMG can be found behind a hard locked gate (use the campfire key)
