Are you perplexed by the criteria to finish The Last Voyage of the ACS Free Market in The Outer Worlds 2? This mission unfolds at Free Market Station, which hosts numerous merchants with fantastic goods. Nevertheless, there is a enigma to unravel, alongside a rather confusing segment referred to as Otto’s Puzzle.
Exploring Free Market Station and Otto’s Puzzle
You will have the chance to journey to Free Market Station after fulfilling the primary goal in Paradise Island and the Vox Relay. Upon reaching the site, you’ll notice two individuals–Guard Seybold and Archivist Stallworth–engaged in a dispute. Converse with them to initiate the quest.
Caution: The objective in this specific mission is to gather details for Stallworth related to a downed vessel. Stallworth poses three inquiries for you, and you’ll gain additional dialogue replies if you’re able to conduct your exploration thoroughly. All these tasks also involve skill checks, so ensure you’ve selected the optimal skills in the game.

Otto’s Information: Part 1 – Engineering skill check or purchases
For The Outer Worlds 2 Last Voyage of the ACS Free Market mission, you will want to head to the merchant area to locate an NPC named Otto Riesling. He is the owner of the Oddments and Gubbin stall. There are three approaches to obtain the information that you require:
- Pass the Engineering 5 skill check.
- Acquire around 1,000 bits worth of goods and select the dialogue option.
- The final method also offers additional rewards, but it comes with a complication. (More on this below.)

Otto’s Information: Part 2 – Otto’s Puzzle
Otto’s Puzzle in The Outer Worlds 2 is truly enigmatic. Here’s what you must understand:
- From your ship’s landing zone, veer left until you spot a Rift Anomaly. Enter the crawlspace, then make another turn and ascend the ladder.
- You will notice a note beside several switches that you can interact with, but nothing will appear out of the ordinary to your naked eye.
- If you wish to observe the invisible wiring, you need to obtain the N-Ray Scanner gadget, found in the Golden Ridge area. You automatically receive it as part of the main quest line in that zone, though it is indeed a lengthy journey.
Assuming you already possess the N-Ray Scanner, activate it while focused on Otto’s Puzzle. You’ll observe the purple wires linking each of the switches. Here are the steps:
- You need to illuminate the lights from top to bottom in sequence. This means pulling the levers in the proper order–i.e., from right to left–according to how they are connected by the wires.
- For the top row, this involves interacting with: 1A and 1B at the top, then 1C (the second from the left in the middle row), followed by 1D (the leftmost switch in the bottom row).
- Repeat this for the remaining two segments once they light up, without pressing a switch again.
However, there is one issue: This puzzle appears to be bugged currently. We managed to complete it during our first playthrough a few days earlier. Regrettably, it seems a recent update has caused problems, as noted by other players. Either way, you can make a mental note about the location of Otto’s Puzzle for a later return.

ACS Free Market Crash Site Information
You can extract further details while in the junkyard adjacent to the puzzle area. There are two damaged sections that you can examine:
- One requires the Brawny trait or Sneak 5.
- The other demands Engineering 8.

Prospero Paolo’s Information
You can also converse with an NPC named Prospero Paolo for The Outer Worlds 2 Last Voyage of the ACS Free Market mission. You will encounter him in the 2nd Choice saloon just past the vendor area.
Before Prospero Paolo reveals any details, you must provide a bottle of Iceberg Aged Whisky. This item is sourced from a nearby bar featuring an NPC named Chef de Mechanique. Unfortunately, Chef de Mechanique will not sell the item because Prospero is requesting it.
- One choice is to pass the Hack 3 skill check while negotiating with Chef de Mechanique.
- A different option is to navigate through the crawlspace exterior to the bar. This enables you to stealthily access the safe behind the NPC provided you have Lockpick 5.

Sub Rosa Archive Information
Lastly, you may collect more information from the Sub Rosa Archive, located in the cellar beneath the 2nd Choice saloon. This can be accessed via the ventilation shaft at the bar/club area. Alternatively, if you’ve previously completed the quest to enlist a companion named Tristan, this section should be available.
Down below, you will encounter a Sub Rosa guard who is napping next to a locked terminal:
- You can force the terminal password if you possess Hack 8.
- Alternatively, if you chose the Lockpick – Pickpocket perk, you can pilfer the document from the guard.
- Lastly, depending on your Sneak skill, you
can simply ambush the guard while they’re unconscious. 

How to reply to Archivist Stallworth
Having collected the information you require, it’s time to converse with Archivist Stallworth. Here are several key considerations:
- Stallworth poses three inquiries:
- What led to the downfall of the ACS Free Market?
- What transpired during the ship’s last moments?
- Were there any factors that contributed to the crash?
 
- As previously stated, the data you’ve gathered should introduce new response choices for each of these questions. You can select any of these choices to acquire bonus bits and XP.
- Nevertheless, you should steer clear of selecting ambiguous responses, such as:
- Response to Question 2: “There was a lot of screaming and chaos, I suppose?”
- Response to Question 2: “[Unwell] I prefer not to think about it.”
- Response to Question 3: “Um, I have no idea.”
- Response to Question 3: “[Deceive] I’m fairly certain the ship was sabotaged by the Order.”
 
Upon completion, Stallworth will express gratitude for your contributions. A few dialogue selections can enhance your reputation with the Sub Rosa faction.
Be aware that there’s one response to avoid: “[Attack] Nobody uses me. Get ready to die.” This incites Stallworth and other guards to become hostile. Consequently, this results in a significant reputation loss with the Sub Rosa faction, which is rather pointless.

What about Guard Seybold’s lockbox?
Now, you may be intrigued about the fate of Guard Seybold. After all, she’s the one being disrespectful to Archivist Stallworth at the beginning of the mission.
If you examine the small structure to the right of the ship’s landing area, you should notice a sizable lockbox. Enter the adjacent room and crouch/stealthily approach Seybold while her back is turned. If you possess the Pickpocket skill, you can take the key without being spotted. Use it to access Seybold’s Lockbox to receive extra bits and XP. And don’t overlook grabbing the collectible card on the desk as well.
This concludes our guide on The Last Voyage of the ACS Free Market quest in The Outer Worlds 2. Remember, numerous other quests are available across different areas. Examples include Pursuit of Purloined Propaganda, Pursuit of the Partite Pentaptych, and Hazard a Gas.
Black market smugglers? Authoritarian regimes? Rampaging Raptidons? Invisible cultists that only appear with special goggles? These antics shouldn’t raise any alarm since we’ve got you covered in our The Outer Worlds 2 guides hub.
