PATHOGENEER

Build the strain. Break the barrier. Trigger the cascade.

PATHOGENEER is a colorful strategy game about building strange fictional strains, releasing them into a living world, and seeing how far they can spread.

BUILD YOUR STRAIN

Choose an EVO trait and shape a branching genome. Improve spread, survival, mutation, host compatibility, and travel routes. Every choice changes how your strain behaves in the field.

BREAK THE HOST BARRIER

Begin with plants, then fight your way into insects, birds, land animals, and even humans. Each host has its own targets, movement patterns, climates, and mutation pathways. Carry successful genes into descendants to build stranger and stronger lineages.

CHOOSE GROUND ZERO

Release into one of 36 ecological zones. Pick a local target, then account for heat, cold, moisture, habitat density, islands, flyways, trade routes, and other movement opportunities.

WATCH THE DAMAGE SPREAD

Follow living infection fronts across the map. Inspect host layers, zoom into regions, and watch for dramatic breakthroughs when a new target establishes, a host barrier breaks, or a distant founder crosses an ocean.

CHANGE THE OUTCOME

Make a small number of meaningful decisions during each run. Reinforce a foothold, ride a migration route, adapt to a climate barrier, preserve an earlier host, or gamble on a distant founder.

GROW A RIDICULOUS LINEAGE

Archive memorable strains with names like Cranky Sneeze Parade and One-Eyed Romaine. Carry inherited mutations into descendants, evolve successful genes through higher tiers, and compare every run's infection, spread, host shifts, deaths, routes, and rewards.

How far can your strangest strain spread?
