After donating blood to Dr. Forsythe, leave the vault and either pursue the Here Kitty, Kitty quest to find Ashes or else wait for 24 hours or more before returning. (You may have to complete another quest in addition to waiting 24 hours before the next scene will trigger). Austin Engill will have been moved to the vault's medical bay. Speaking with Dr. Penske begins the quest.
Austin was bitten by a mole rat when wandering in a secret partition of Vault 81 and subsequently fell ill. The player must follow Bobby De Luca to the entrance hidden in the reactor room. They are asked to go into that part of the vault and find a cure. During the investigation, they must fight their way through run-down rooms full of Vault 81 lab mole rats, which will transmit a disease if they manage to bite the Sole Survivor, conferring a potentially permanent loss of 10 HP. The true purpose of Vault 81 as an infectious disease incubation and vaccine development facility is also discovered. In the final area there is a terminal that must be hacked or unlocked with a password in the far room on the upper floor past a mole rat brood mother. The password to the locked terminal is next to the research comm terminal in the subsequent room. After this the player finds a robot named Curie who has manufactured the cure; however, there is only one dose left. Curie follows the player out of the secret vault up an elevator back to the locked door by the main vault's entrance. The player must then return to Dr. Forsythe in the medical bay with the cure and make a choice:
Option 1: Give Austin the cureEdit
If the player character gives the cure to Dr. Forsythe, they receive rewards including the syringer rifle and a room in Vault 81. Most items throughout the vault are no longer marked as owned and can be freely picked up without angering the residents. As a side effect, if the player character has contracted the disease during this quest, they keep the disease.
Option 2: Deny Austin the cureEdit
No matter whether it's by directly refusing it in dialogue (requires selecting "Only one, it's mine" followed by "Let him die") selling or losing it, or using it on yourself (possibly to cure your own mole rat disease), all of these options are treated the same; Austin dies and everyone in Vault 81 blames the Sole Survivor. A small memorial for him is prepared in the classroom under the "America lives on... in you" poster, consisting of a candle, a new teal flared vase, a toy car, a baseball glove and a teddy bear.
Either way, the quest concludes and Curie asks to accompany the Sole Survivor around the Commonwealth in order to further her scientific research, becoming available as a companion.
- Cait, MacCready, and X6-88 dislike giving Austin the cure and like keeping it for yourself.
- Danse likes giving Austin the cure and dislikes keeping it.
- Codsworth, Preston, Piper, Hancock, and Nick love giving Austin the cure and hate keeping it.
- Strong likes either outcome.
- All but two companions (Danse and Deacon) dislike the option to split the cure, "good" companions for being selfish and "evil" companions for offering even that much of it to Austin. Danse doesn't care, and Deacon likes this option, as well as loves giving Austin the full cure and dislikes keeping it.
- There are no affinity changes for the second set of dialogue after keeping the cure for yourself, whether you back down and decide to give it to Austin after all, or stand by condemning Austin to death, so affinity changes are reflected in the first choice only.
- Dr. Penske is essential to the quest, so if she dies before starting this quest, you will be unable to obtain Curie as a companion.
- After completing this quest, items in Vault 81 can be taken without being considered as stealing, with the exception of items within personal residences and the overseer's office.
- The higher the player character's Endurance, the lower the chance of contracting the disease on any particular bite. Keep in mind that the chance is never zero.
- The mole rat disease is one of the very few status effects that not even the game's god mode command, tgm, can make the player immune to.
- It is regarded as a perk, 0023aec1, so using player.removeperk 23aec1 can remove the effect afterwards.
- Selecting the "We'll split it" option results in an angry reaction from Dr. Forsythe, who will respond by saying that it doesn't work that way, and will chastise you for being selfish. Many companions will respond negatively to choosing this option, after which you can return to the original choice of keeping the whole cure for yourself or giving the whole cure to Austin.
- If hacking the expert-locked "Vault 81 secure access terminal" to gain entry to the room with Curie and bypass the final pack of mole rats, they will remain, but Curie will not open the door until you go back and kill all of the rats.
- It is possible to exploit the game's ability to "walk away" in mid-conversation in order to cure both Austin and yourself:
- Select the dialogue of your choice, then push the left stick/movement keys until the camera cuts away from a closeup of Dr. Forsythe.
- Turn the player's view away from Dr. Forsythe so the dialogue options disappear and the Pip-Boy becomes accessible.
- Open the Pip-Boy, use the cure (or drop it), and exit, turning back to face Dr. Forsythe.
- With "Give it to Austin" you have a narrow window to pull this off before it is removed from your inventory, and with "Only one, it's mine" the "Just kidding" and "You're right" followup options remain as though you still have a cure to hand over. Note that companions will approve or disapprove of the action taken.
- The player should keep in mind that if they decide to keep the cure for themselves, they will not be able to start or finish the quest Short Stories.
- It is possible to make it through the secret vault without contracting the disease. Simply killing all the mole rats before they can strike the player, companions, or the protectrons will prevent infection, as these events trigger the disease. Jet and similar are recommended to slow time, use of V.A.T.S., as well as running solo through the vault. Finally avoid dirt areas, and try camping in corners, and on crates while waiting for the spawned mole rats to approach. The sound of mole rats popping out of the ground is the cue to sprint to a safe corner and sneaking can indicate when the vault is cleared.
- If you have a traveling companion with you and they get bit, you will contract the disease. However, you won't contract the disease by looting dead mole rats.
- The mole rat that has bitten Austin can be found on the bed inside the room in the clinic when Dr. Jacob Forsythe explains Austin's diagnosis to Dr. Penske. The mole rat will be gone when the cure is obtained.
- pc ps4 xboxone If any companion or any type of creature not hostile to the player character, including the hackable protectron in the area, gets hit by one of the diseased mole rats, then the player character will get the disease, as if they had been bitten instead.[verified]
- pc ps4 xboxone If you leave the vault before Bobby opens the secret door, he will have gone into the secret vault with the secret door still being closed, making it impossible to finish the quest.[verified]
- pc ps4 xboxone Sometimes, the cure will duplicate when picked up by the player, making it possible for the player to cure themselves and Austin at the same time.[verified]
- pc ps4 xboxone Sometimes Dr. Penske will not be in the room discussing her grandson's illness with Dr. Forsythe and the quest will not start.[verified]
- This can be resolved by going to Dr. Penske's office, and talking to her there to start the quest.
- If Dr. Penske has been killed the discussion will never begin causing the quest to become glitched rendering it unable to be completed.
