How to Solve The Mystifying Case of the Midnight Marauder in The Outer Worlds 2

Besides the Observatory puzzle, The Outer Worlds 2 has many side quests, such as the Mystifying Case of the Midnight Marauder. One of the earliest and most mysterious side quests in this popular FPS RPG from the developers behind Grounded 2, The Mystifying Case of the Midnight Marauder is an optional mission that lets you flex your observation and decision-making skills while uncovering a small hidden story in Paradise Island.

Here’s a complete walkthrough on how to solve the Mystifying Case of the Midnight Marauder in The Outer Worlds 2 quickly and efficiently.

Starting The Mystifying Case of the Midnight Marauder

You’ll first hear about The Mystifying Case of the Midnight Marauder while exploring Paradise Island — particularly in Fairfield. As you go through terminals in the area, you’ll eventually come across a message labeled “Contingencies.” Reading this entry will automatically trigger the hidden quest and set you on the path toward the Midnight Marauder mystery.

Finding the Right House

Once the quest begins, make your way to the housing row located near the greenhouse exit. The house you’re looking for is the first one on that stretch. You’ll recognize it easily — it has a terminal inside and a nearby switch that sparks with electricity.

Interact with the terminal and open the “Contingencies” file to officially start the quest.

Locating the Hidden Cellar

The entry in the terminal hints at a secret cellar, but finding it can take some time unless you boost your Observation skill. You don’t need a high skill level — even three points in Observation are enough to reveal what you need.

After reading the entry, step outside and head to the left side of the house (the same one with the terminal).
Look carefully at the wall on that side — if your Observation skill is high enough, you’ll see a small eye icon appear.
This marker indicates something hidden nearby.

Move closer to that section of the wall, and a blue glow will appear, revealing a hidden cellar door. Interact with it to open the passage and head downstairs to continue the quest.

What’s Inside the Cellar

Inside, you’ll find a small group of NPCs hiding underground. This is where The Mystifying Case of the Midnight Marauder turns into a true Outer Worlds experience — your dialogue choices will decide what happens next.

You can approach the situation diplomatically, investigate further, or go for a more aggressive route.
In our playthrough, we chose the violent approach, which immediately triggered a chaotic confrontation.

Regardless of how you decide to handle the encounter, the outcome will be similar — you’ll earn experience points, gain access to new dialogue options, and collect a bit of loot from the cellar and the nearby area.
