Virus Wars is a two-player board game that simulates an evolution of two colonies of viruses, which are growing and absorbing (zombifying) each other. The exact origin of the game is unknown but it was actively played as a paper-and-pencil game in Saint Petersburg State University in 80s. There were several variants of the game with slightly different rules.

A player must do all 5 steps per his turn. If a player is unable to do all 5 steps then the player loses the game.
