Its fun to play with virus colonies is it? Yes, yes it is.
In this great 2 player strategy game, each player grows his colony of viruses into the petrie dish and under good conditions can zombify some viruses to gain advantages and position themselves for a win!
To win is not a simple task however: you must leave your opponent with no legal moves while he tries to do the same to you.
Play against people from around the world, compete, play ranked (to cumulate ELO Rankings) and unranked games for fun.
