The game takes place in 2040. From the headquarters of the Arctic comes a statement about the search for new organisms. You and your team set off on a research expedition to study unknown organisms.
The study gets out of control, and one or more people are infected with the new unknown deadly virus "Virus-40". The virus clouds people's minds and forces them to infect others with a deadly virus in order to destroy the expedition.
Players are divided into 2 roles:
•Infected - whose main goal is to infect everyone else, to deny being infection and blend in with other members of the expedition.
•Healthy - find the infected person and cure him/her with an antidote and prove that you are healthy to others, and also to survive it is necessary to maintain the station in staff state.
