The human suffering in The Last of Us is underscored by the visible suffering of the infected themselves. Some who—fleetingly—still have control of themselves are tortured by their very existence. Bringing creatures like that into Pathfinder was an obvious decision, but developing them outward from the original design was also a strong intention. While the cordyceps infected shown in the game are relegated to humans alone (though concept art for cordyceps infected animals was made in pre-production, they had to be cut) the infected featured below can come from any corporeal, living creature capable of being ravaged by disease.
If someone would like to do fanart of cordyceps infected monsters, I'd love to see it and will gladly showcase it here!
Enjoy the cordyceps-related nightmares below, and let us know what you think of them in the comments!
