Pathogen: be the virus

Be the virus. Infect a host organ by organ, then infect the world.

A roguelite where you play a single virion fighting real immune cells from the nose to the brain. Auto-fire, dodge, mutate, and build a lineage that gets nastier with every generation.

How it plays

Most games ask you to stop the outbreak. This one makes you the outbreak.

STEP 1

Infect

Pick a host with a hidden genome of strengths and weaknesses, and drop into its nose.

STEP 2

Fight

Your virus fires on its own. You move and dodge through waves of real immune cells.

STEP 3

Mutate

Grab traits as you go and stack them into a build: burning, piercing, bouncing, orbiting shots and more.

STEP 4

Spread

Beat each organ's boss to break into the next, all the way to the brain.

Four viruses, four ways to play

Every lineage starts as Influenza A. Level up to unlock the others. Your level, skill tree, Petri Lab and gear carry over whichever virus you play.

The Shapeshifter

Influenza A

Starter

The virus every lineage starts as. Its shots keep mutating between four types, its Antigenic Shift fires every mutation at once, and its Pandemic ultimate infects every cell nearby.

The Turncoat

Retrovirus

Level 4 unlock

Turns the immune system against itself. Cells killed by its shots go into a reservoir, and Integration Surge releases them as allies. Latency hides it completely.

The Hemorrhager

Filovirus

Level 12 unlock

Makes cells bleed. Its hits can start bleeds, Hemorrhage makes every cell nearby bleed heavily and hit softer, and Viral Hemorrhage takes a third of their health while healing you.

The Superspreader

Halovirus

Level 8 unlock

Fast and quiet. It fires spike volleys, cycles through three variant forms, and its Superspreader Event turns a crowd of cells into a chain of outbreaks.
