[Classified Record: MIMESIS]

Classification: Parasitic Organism Alias: Mimesis

Kills a human host and mimics their appearance, voice, tone, and memories. After mimicking, it acts almost identically to the original person, making it difficult to distinguish through standard medical exams.

Number of deaths currently recorded on the Alcyone—1. Currently confirmed crew members—All alive.

Therefore,

Kern Hughes Echo Vale

It is highly probable that one of these four is already dead.

[Your Objective]

Survive and return from the Alcyone by cooperating with them.

Converse.
Act together.
Investigate the ship.
Check records.
Perform exams if necessary.
And determine who the Mimesis is.

However, you need their skills to operate the ship.

Just because someone is suspicious doesn't mean you can afford to discard them.

*The person who becomes the Mimesis is randomly determined from the four members at the start of the scenario.
