Blend in during the day, fake your puzzle progress, and sow chaos in the chat. When the lights go out, use the secret "Hive Link" to coordinate with your fellow Parasites. Vote to assassinate crewmates in the dark, or trigger a bio-infection to force a crewmate into an ultimatum: join the Hive, or face immediate elimination.
