In Viral, each player controls a virus that is growing inside a human body. Players will simultaneously play cards to place tokens on the board and move them around to gain control of zones to score Viral Points. Players also score points when they cause a crisis in an organ, thus activating the anti-virus. Players also can play cards that allows them to attack other players. Tje Hive Expansion gives each player an asymmetric power and a hive to store virus tokens. The player with the most Viral Points when the event deck runs out is the winner.
