Bloodborne Cave

 is located east of the Brotherhood of Steel Safehouse and northwest of Bitter Springs. A large number of Night stalkers and the 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 Key. This key opens a Very 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.

If the Courier has Animal Friend the Night Stalkers in the cave will be friendly making it easy and safe to explore, and gather Night Stalker eggs for The Thorn.

Notable loot
The cave's loot is located within a Very Hard lock mid-way through the cave. There is a key for the gate on the bricks of the campfire. Be very careful; there is a tripwire immediately below the gate that if hit, will cause 9 frag grenades to drop and more than likely kill the player in any level, even with med-x, or any armor. Also, if you have the marked cards, you can easily disarm and collect the grenades.
 * Over 7000 bottle caps in an Average-locked box which is behind a very hard locked gate (Quantity may vary by several thousand).
 * Over 400 NCR dollars and some Legion money
 * A Hunting revolver and ammo can also be found next to a skeleton around the camp fire.
 * A 12.7mm Pistol and ammo can be found next to a skeleton in the last section of the cave with the ledge.
 * A Hunting shotgun and some 12 gauge shotgun shell can be found around the camp fire.
 * A 12.7mm SMG and ammo can be found behind a hard locked gate (use the campfire key).
