Main Hall consists of six rooms and a corridor connecting them. Three of these rooms appear to be bedrooms, one of which contains a ladder leading to Electrical and another which contains a vent. This vent leads to the vents in Engine Room and Kitchen. There is also a room full of cleaning supplies, which contains a vent that leads to either side of Gap Room, a room which contains the pipe used to Decontaminate, and a darkroom for completing Develop Photos. This room does not seem to have any lighting, as when a Crewmate enters, their vision shrinks as if Fix Lights was ongoing. Players outside of the room cannot see inside. The left exit of this room leads to Engine Room, while the right leads to Showers.

- In the middle of the Main Hall, a can of beans can be seen, which could be a reference to the can of beans Henry Stickmin uses in The Henry Stickmin Collection during the Relentless Bounty Hunter route.
- A chest can also be seen in the bedroom at the top-left, which is a secret in Infiltrating the Airship.
