The goal of this quest is to answer all three of Stallworth's questions when reporting your findings. That means, you don't need to unearth every bit of info, just the ones that can answer all three of the questions.
| Questions | Possible Answers |
|---|---|
| Question 1 |
Otto's Info ┣ Solve Otto's Puzzle OR ┗ Pass an Engineering 5 Check Examine the Destroyed Engines ┗ Pass an Engineering 8 Check Hack the Sub Rosa Archive ┣ Steal the Terminal Password OR ┗ Pass a Hack 8 Check Acquire Prospero's Information ┣ Pass a Hack 3 Check OR ┗ Pass a Lockpick 5 Check |
| Question 2 |
Acquire the Buried Audio Log ┣ Pass a Trait: Brawny Check OR ┗ Pass a Sneak 5 Check Acquire Prospero's Information ┣ Pass a Hack 3 Check OR ┗ Pass a Lockpick 5 Check |
| Question 3 |
Otto's Info ┣ Solve Otto's Puzzle OR ┗ Pass an Engineering 5 Check Hack the Sub Rosa Archive ┣ Steal the Terminal Password OR ┗ Pass a Hack 8 Check |
Aside from Otto's testimony, in order to get the full rewards of this side quest, you'll need to get either the Audio Log (requires Trait: Brawny or Sneak 5) or Prospero's Info (requires Hack 3 or Lockpick 5). Without either, you won't get the full side quest rewards.
| Step-by-step Walkthrough | |
|---|---|
| 1 | ![]() Otto's info is the easiest to get since you won't need to pass any skill checks. To start, head over to the area with the Rift Anomaly in Free Market Station. Note: If you have Engineering 5, you can skip the puzzle and head straight to Otto. However, you'll miss out on a few rewards from his safe. |
| 2 | ![]() Crouch through the opening and follow the L-shaped hallway. Climb the ladder at the end to reach Otto's puzzle room. |
| 3 | ![]() Pull the levers in the order shown above to solve Otto's puzzle and open the door to his hideout. Note: This is typically solved by using the N-Ray Scanner - a gadget you get from the N-Ray Range in Golden Ridge, during the main quest. |
| 4 | ![]() Read Otto's Soot-Smeared Journal on the ground to obtain the info you need to interrogate him. Before leaving, make sure to loot the safe to get x1 Advanced Decryption Key and Bit Cartridges, as well as the Triple Barrel Shotgun. |
| 5 | ![]() After reading Otto's journal, head over to the Free Market Bazaar and look for the stall called Oddments & Gubbin. Speak to Otto and ask him about the ACS Free Market. You can use either of these 2 dialogue options to get him to talk: ① I read your journal, and what happened to you. Talking's the first step to getting better. ② Engineering 5: Tinkering's hard enough when you're focused. And you aren't focused. |

Once you've investigated all possible sources, head back to Archivist Stallworth and report your findings. Remember, it does not matter what you tell her as long as you have one plausible answer for each of her 3 questions.
Pick from the answers listed below to get the full rewards for this side quest:
| Questions and Answers | |
|---|---|
| 1 |
Stallworth: ...how did the ACS Free Market meet its end? Possible Answers: ① Otto's Info: A survivor told me it was a vengeful engineer. ② Engine Debris: I found some debris suggesting the engines both exploded. ③ Prospero's Info: A local gossip mentioned it was due to a heartbroken captain. ④ Sub Rosa Archive: Some documents in the Sub Rosa Archive seemed to record an enemy agent causing the crash. |
| 2 |
Stallworth: Aside from the crash, what occurred in the ship's final moments? Possible Answers: ① Audio Log: According to a recording, someone other than the captain was trying to stop the nosedive. ② Propsero's Info: The crew tried to overpower the captain, but they weren't able to stop her. Do not pick any other options aside from the above. |
| 3 |
Stallworth: Last question: were there any contributing factors to the crash? Anything that might recontextualize what actually happened? Possible Answers: ① Otto's Info: One of the ship's chief engineers was demoted right before the crash. ② Sub Rosa Archive: Auntie's leadership put a salvage contract on the ship, then stripped it after the crash. Do not pick any other options aside from the above. |

The rewards for The Last Voyage of the ACS Free Market will depend entirely on the answers you relay to Archivist Stallworth. You need to fill in the blanks for all three of her questions to get the full 1301 Bit Cartridges and XP.
If you fail to provide enough info during one or more rounds of questioning, you will get a reduced number of bits from Stallworth.
If you answered all three questions posed by Stallworth, you'll get +3 Reputation for the Order of the Ascendant. You can get an extra +3 Order Reputation by passing a Speech 3 check during the final conversation:
| 1 | So what did you conclude from what I gave you? |
|---|---|
| 2 | Wait, what? I thought you were compiling a historical report! |
| 3 | Speech 3: Put in some good words with your fellows and I might be willing to let this slide. |
Note: If you have Sneak 5, you can get an extra +150 Bit Cartridges from Stallworth. However, doing this locks you out of the +3 extra Order Reputation dialogue choice.
If you aren't rocking a Speech build then you can still get an extra +1 Order Reputation during this conversation. Follow the choices below to get that extra rep during your run:
| 1 | So what did you conclude from what I gave you? |
|---|---|
| 2 | Keeping every option open to further the war effort? I like it. |
