How Little We Know is a side quest in Fallout: New Vegas.


The Omertas have an unsavory reputation, and it is not undeserved. They are planning something devious and investigation into it is needed.


Working with Cachino

  1. Enter Gomorrah and speak with the front receptionist.
  2. Find proof that Cachino is pulling in work on the side; this is done by blackmailing him with his journal, found inside his room. The key to the room can be bought from the receptionist with 300 caps (a Barter check of 55 lowers it to 200) or by intimidating her with a Strength of 8.
  3. Talk to Cachino about suspicious deals in Gomorrah.
  4. Talk to Clanden, return to Cachino and then get rid of Clanden. The snuff tapes in Clanden's safe can be taken back to Cachino to open up dialogue to confront Clanden.
  5. Get Troike out of his contract. This can be done by convincing Big Sal with a Speech of 53 or a Barter of 45. With a Speech of 80, the Courier can lie to Troike and threaten to tell the New California Republic about his dealings. Alternatively, the Troike blackmail note can be presented to Captain Marie Pappas at the NCR Embassy.
  6. Destroy the weapon shipment Troike got in the casino basement using he thermite provided. Alternatively, a Speech of 70 convinces Troike to destroy the guns himself, but he will rat out the Courier when he is caught.
  7. Get rid of the Gomorrah bosses. A Speech check of 80 with Big Sal will convince him that Nero was working against him. Sal will kill Nero, leaving only Sal to take care of.

Working with the bosses

  1. Talk to the bosses (Big Sal and Nero).
  2. Show Big Sal Cachino's journal.
  3. Help Clanden and Troike with their projects.
    1. Clanden wants to kill a large amount of people in a short amount of time; with a Science of 60, the Courier can suggest a chlorine bomb. A container of chlorine can be stolen from a supply closet in the Ultra-Luxe behind the counter where Mortimer stands, or the chlorine can be purchased from Ralph of Mick & Ralph's. Ralph can be convinced to give it for free with a Science check of 60.
    2. Troike had a crate of guns stolen by the Fiends. Retrieve the disassembled weapons shipment northwest of the Sunset Sarsaparilla headquarters.
  4. Return to Big Sal.

Quest stages

1 Talk to the receptionist in Gomorrah about Omerta activities.
2 Talk to Cachino about suspicious Omerta activities, perhaps someone else in Gomorrah knows how to find him.
3 Check Cachino's room or his person for some proof of his behavior. Perhaps someone has a key to his room.
4 Cachino's Journal should have enough proof to get him talking.
5 Sell Cachino's Journal back to him and help take down the bosses, or show it to the bosses to get on their good side.
6 Talk to Troike about mysterious gun shipments.
7 Find out what kind of work Clanden does for the family.
8 (Optional) Kill Clanden.
9 Clanden has been taken care of, and won't be able to help the Omertas anymore. Cachino should be informed.
10Quest finishedCachino has agreed to take out the Omerta bosses during our meeting with them. Go to Cachino when you are ready.


  • If you are working or intend to work for Caesar's Legion, it is recommended that you complete this quest by exposing Cachino to Big Sal and Nero, otherwise you will ruin their grand plan, which you will learn is actually Caesar's plan. If you complete it by taking the Cachino route, Caesar will become very angry when you speak to him next and threaten you with death unless you have helped them out before, but will only spare you this one time. You must confess any crimes you have committed against him when you are given the opportunity; if you do not, then you will turn the Legion hostile the next time you enter dialogue with Caesar.
  • Completing this quest before Bye Bye Love will result in that quest failing or becoming unobtainable, as Joana and Carlitos will disappear.
  • If the weapons cache is destroyed using Troike's thermite, the parts of several recognizable weapons can be seen lodged in the melted debris. Most notably this includes a Chinese assault rifle, with only a few inches of the barrel and its attached iron sight visible.
  • If you want to obtain the Pimp-Boy 3 Billion, you have to free Troike from his contract by convincing Big Sal to let him go. If you use the evidence to get Troike to let you destory the guns, you will not be able to get the alternate Pip-Boy.
  • Confronting Clanden can result in him becoming hostile and attacking.
  • Killing Clanden before you are instructed to can result in failure of the quest but the player still receives the same rewards (positive karma, experience, etc.). Same goes for Cachino.
  • It is possible to do this quest the "good" way and still obtain the Pimp-Boy 3 Billion. You have to get Troike out of his contract and make sure to talk to Big Sal about the guns from Mick and Ralph's before you kill him at the end of the quest.

Behind the scenes


  • PCIcon pc.png PlayStation 3Icon ps3.png Xbox 360Icon xbox360.png If you don't speak to Liza O'Malley before starting How Little We Know then you will not be able to speak to Cassandra Moore upon returning to Hoover Dam. As such, you are unable to complete For the Republic, Part 2.
  • PCIcon pc.png PlayStation 3Icon ps3.png Xbox 360Icon xbox360.png When speaking to Cachino before going to kill the bosses, selecting the "Wait" and "Ready" dialogue options may prevent Cachino from further interacting with the player. When trying to re-initiate dialogue, Cachino will only respond that 'there is no time to talk' meaning the player cannot tell him they are ready to go; and he will also remain in place and not lead the player to the meeting with the bosses, preventing further progress in the quest. Leaving Cachino there and attempting to finish to quest later will revert Cachino to previous lines of dialogue in which you can only ask about the bosses' plans, Troike, and Clanden.
    • This bug can be bypassed by simply finding the small office where the meeting would take place (next to Big Sal's office on the main floor) and killing the bosses, resulting in a quest complete message, regardless of Cachino following you there.
    • It is possible to fix this by taking the elevator to the main floor, then typing prid 11118d followed by moveto player in the console to bring Cachino to the main floor. Once Cachino gets to the main floor, he walks normally to the bosses' room and the usual sequence of events proceeds.
  • PCIcon pc.png PlayStation 3Icon ps3.png Xbox 360Icon xbox360.png The dead prostitute you can inspect during "How Little We Know" can be found alive and standing before, during, or after the quest is complete. If you examine her the box telling you to inspect her will still pop up.
  • PCIcon pc.png Xbox 360Icon xbox360.png Sometimes, after completing How Little We Know, you can't tell Mick that the Omertas are buying his weapons again. To work around this, before telling Troike to destroy the weapons, have his contract destroyed by talking to Big Sal before completing the quest. Then tell Troike he is free and then tell him to destroy to the guns. Note that if you find the Troike blackmail note before talking to Troike about the prostitute, although Troike will still have the dialogue asking for help getting out of his contract, Big Sal will not have the related dialogue, so you cannot get Troike out of his contract, thus never tell Mick that the Omertas are buying guns again, and thus never get the Pimp-Boy 3 Billion.
    • PCIcon pc.png One fix with the console is to use SetObjectiveCompleted 00110A63 50 0, SetObjectiveCompleted 00110A63 51 0, and SetObjectiveDisplayed 00110A63 51 1 to put yourself back to the stage when Big Sal has the dialogue.
  • PlayStation 3Icon ps3.png Xbox 360Icon xbox360.png If you attack the dead bodies of Big Sal and Nero after killing them, you will continue to gain experience. This can vary from 50 experience points to 750 experience points each hit.
  • PlayStation 3Icon ps3.png Xbox 360Icon xbox360.png When Cachino is supposed to give you the sawed-off shotgun, it may end up in your companion's inventory instead of yours. This can occur even if Cachino is still bugged as previously mentioned.
  • PCIcon pc.png PlayStation 3Icon ps3.png If you side with Cachino for this quest, then go talk to Clanden without having the evidence to progress in dialogue, then see Troike and finish his objective, reporting back to Cachino will cause him to tell you that it's time to take out the bosses, bypassing Clanden's portion of the quest altogether.
  • PCIcon pc.png Xbox 360Icon xbox360.png Killing Clanden may cause ED-E to stop following the player (it just gets stuck). Making ED-E wait won't help. Ordering it to return to base, then quickly killing Clanden and rehiring ED-E will help. The same thing may happen when killing Big Sal and Nero.
  • PCIcon pc.png The dialogue option that starts this quest can appear without doing Bye Bye Love or starting For the Republic, Part 2, for no apparent reason.
  • PCIcon pc.png After talking to Big Sal and telling him of Cachino's treachery, going into his office to have a 'little talk', button man remains immobile, Cachino just sits there and none of them will speak with you anymore.
  • PCIcon pc.png Sometimes, after planting the thermite charge, the switch won't set off the explosives.
  • PCIcon pc.png If you steal Sal and Nero's ammunition before sitting down for your chat, choosing the lie option implicating Nero will cause the two of them to stare at one another with guns out, but they will not attack due to lack of ammunition.
  • PlayStation 3Icon ps3.png After picking up the blackmail tape, you cannot negotiate Troike's contract with Big Sal. This means you cannot free him and get the Pimp Boy. At this stage, you also cannot turn in Cachino, as he will have his diary back (pickpocketing it does nothing) meaning there is no way to get the Pimp Boy at all. To get around this the courier must kill Cachino then talk to Big Sal who will buy the guns from Mick and Ralph if the courier selects the 50 speech check. Doing this will fail the mission but grant the player the Pimp Boy after talking to Mike.
  • Xbox 360Icon xbox360.png If you proceed with killing Cachino and beginning the quests for the Omertas family, the receptionist that Mr. House sends to speak with you during The House Always Wins Part IV, may not give you the necessary speech options.
  • Xbox 360Icon xbox360.png After receiving the option from Cachino to kill Clanden, occasionally, killing Clanden will result in a failed quest.
  • Xbox 360Icon xbox360.png If the player chooses to bypass the quest and instead simply kill the Omertas, Big Sal may not necessarily become hostile. It is possible to approach him after fighting through the rest of the main floor and pass the Speech 50 check to convince him to buy from Mick and Ralph's. This will also advance For the Republic, Part 2 and prompt the player to lie to Colonel Moore even if the Omertas have been eliminated.
