Roles:
1 bioterrorist
1 bioterrorist assistant
5 compulsive company fruit vendors (does not leave any fruit message, just visits)
1 company HR (flavored neapolitian, returns a "company fruit vendor" or "this person studies diseases" result)
1 company epidemiologist (shows if target is infected or not, cannot be infected from visiting an infected target/bioterrorist but can be infected from a bioterroist or infected person visit)
bioterrorist has an infection mechanic. Fruit company aligned players will not know who is infected, but the bioterrorist team does, and the bioterrorist team is immune to infection.
If the bioterrorist dies the assistant takes their place. The bioterrorist assistant does not spread the infection if visited. The bioterrorist team has night chat.
The bioterrorist chooses to visit a target each night. That target is infected at the start of the next day.
Any infected target that visits a non infected target becomes infected at the start of the next day, and any infected target that is visited by a non infected target infects that target as well.
Once everyone is infected, everyone gets a public message that they are dying, and die at the end of the day unless the bioterrorist team is elimed, result in a company loss and bioterrorist win. If the company is dying and the bioterrorist and bioterrorist assistant are still alive, the bioterrorists win.
Still deciding day and night phase length.
Edit: the bioterrorists have day talk
Edit2: Doing 14 hour days, 10 hour nights, with a 24 hour day 1.
