Many portions of the cave are slightly irradiated. It appears that, before the Great War, the cave was used as a toxic waste dump site. Additionally, someone set up a lab on a radiation-free ledge where they could study the giant rats that are found thriving amid the hazardous conditions.
From the entrance, the path forks. The left path leads into an irradiated room (1-2 rads per second that fills the whole barrel-filled cavern) where a skeleton with a knife, .357 magnum revolver and an ammunition box sit in the middle, along with a copy of Lad's Life. This loot may not be worth the hassle & rads, as even with the Scrounger perk, the ammunition box only contains a small amount of ammunition.
The right path forks again after the descending path winds past mine carts with barrels in them and flattens out into a small cave. The right fork from here goes up to a ledge with a view over the main irradiated cave chamber, then leads to a recessed room containing a broken fence. Through this fence is the Ratslayer, medical equipment and ammunition boxes. Notable items include two stimpaks and one Med-X on the table that are in front of the player when they pass the fence, and a Programmer's Digest on the farthest right table. On the desk where the Ratslayer is found there are two RadAways, one stimpak, a Cateye, another Cateye on top of the computer, another Progammer's Digest and a copy of Today's Physician. There is a Sunset Sarsaparilla Crate to the right of the desk. On top of it lies a radiation suit. The left path leads to a final cavern, where Jane's brahmin will spawn for the Debt Collector quest.
As the name suggests, Broc Flower Cave is obviously named after the high concentration of broc flowers outside of the cave. This could also be considered the highest concentration of broc flowers in the game.
Inside the lab where the Ratslayer is located, there's half of a first aid box sticking out of the floor near the other first aid box hidden under a table. It seems like this first aid box was placed there by mistake by the creators of the level because of the weird placement, and the fact that it's very near the other first aid box.
Radiation levels can range from 1-3 rads\sec, up to even 20 when drinking the water - being well stocked with Rad-X is highly recommended.
Since the cave is so close to a Legion camp, the player will find many veteran and recruit legionaries and 1-2 veteran decanii around the cave. They are armed with machetes, throwing spears, fire axes, and a couple even have trail carbines.
A small group of NCR soldiers from Camp Searchlight may also be found fighting the legion not far from the cave.
xbox360ps3pc If the player enters the cave before Lady Jane tells them about her lost caravan, the brahmin will not be there if they return to the cave for the Debt Collector quest. Thankfully, the player can lie about collecting the caps and pay off all of the debts themselves. Jane's brahmin can also be placed near the player using the console (PC). Enter "player.placeatme 116af4".[verified]
