In Germ War: Invaders, you are a newly introduced germ in a petri dish, surrounded by hostile germs. One section at a time, you will have to fight the “home team” in order to gain superiority of the petri dish. Germ War: Invaders is a solo (with a two-player option), area control game using a traditional deck of cards. Each turn you will place your cards on the petri dish by their value, trying to gain and maintain the majority control of the sections to win the game. In the solo game, you will play again the AI who can spread very quickly in the petri dish through a chain reaction but is limited on his growth ability. In the two-player game, its germ vs. germ. Both have the same ability, so the trick is to play the most efficient game.
