Pathogenesis 2.0

Pathogenesis is a deck building game in which players take on the role of bacterial pathogens attacking a human host. The pathogens must survive the body's powerful immune response, adapt in an ever changing environment, and evolve to take on virulence factors to increase their attack, defense, and other abilities so that they may do enough damage to defeat the body before the human host becomes immune and all the players lose the game.

Pathogenesis STD adds the fourth tract to the body, the Genitourinary tract, introducing pathogens, traits, and virulence factors appropriate for this area of the body. Further, keeping to the science, the Genitourinary tract has no toxin cards but instead a new mechanic has been introduced, Collateral Damage cards!
