I want to praise the overall style, especially the room descriptions and NPCs have this brilliant, almost The Office-like corporate deadpan humor to them that grounds the sci-fi setting so well!
A few minor additions would improve the game at the table: the text describes a Medbay, but it’s missing from both floor plans.
The hook about ocean creatures holding a potential vaccine is awesome, some concrete ideas or checks on how the PCs could actually study, or sample them to isolate a cure would be super helpful. The same for NPCs: threat levels or tags would help GMs run conflicts smoothly.
A brief guide or framework on how to roll/structure the adventure (like infection progression clocks, containment check intervals, paranoia clocks...) would give GMs an immediate roadmap.
Overall, I think it's a deeply atmospheric and funny sci-fi survival scenario with fantastic potential.
