Inside the vault are numerous mantises and spore carriers hidden in plant beds. The door is permanently open and has a curtain of overgrown plants. There are also four giant mantises hiding in the foliage.

There are large and colorful plants outside the entrance, and a sign saying, "Stay Out! The Plants Kill!". Quite a few cazadores roam the area near the vault. The vault is easily found by following the map marker. To get this option, one must not have delivered the invoice from the Crimson Caravan, or one will only have the option to say goodbye (fixed or not always happening) If he is spoken to again before heading to Vault 22, one can demand that he double the caps he is paying for the job (40 Speech is required). Hildern has sent others on this task but none of them have returned. Before leaving the base, make sure to speak to Angela Williams in order to get the optional objective to find Keely, a researcher who went to the vault before and is now missing. He will give the player character the location to Vault 22 and ask them to enter and download the experimental data onto their Pip-Boy. After speaking to him, he will tell the Courier that Vault 22 has data on its computers that will help prevent a future food shortage.

Hildern can be found in his office located inside the Camp McCarran terminal building on the east side of the terminal in the south wing.
