In Viral Counter Attack, colonies of "art viruses" are slowly destroying digital paintings. They "eat" the images to survive and generate offspring.
Players compete or cooperate to control artifial viral colonies. They have to move their bodies to guide the movements of the virus on the screen.
Overhead cameras capture the direction and the intensity of players' movements. The data is automatically translated in real time on the activity of the viruses.
Each gamer can control one colony (identified by a colour) and they have to survive as long as possible by guiding the colony towards areas "rich with nutritious resources". But they can also attack other colonies.
