Mutacronia: hidden threat
Demo available
About the game
You are a detective inside a living organism — and every mutation turns you closer to the infection you’re trying to stop.
Original Steam description
A 2D platformer with detective elements set inside a living organism.
The world is calm… or so it seems. Rumors about a mysterious “Cough” spread through the system, dismissed by most as nonsense. But something is wrong. Cells are changing. The balance is breaking. The world is going down.
You play as Leukocyte, a detective immune cell tasked with uncovering the truth. Question inhabitants, follow leads, and expose a conspiracy that reaches deeper than expected.

INVESTIGATE THE UNKNOWN
Explore interconnected biological zones and gather clues:
talk to inhabitants
uncover hidden connections
make sense of conflicting stories
Not everyone is telling the truth.

COMBAT
Fight your way through infected areas:
mutated enemies and unique bosses
attacks with organic, living weapon
Try to survive.

RISKY MUTATION
Gain power at a cost.
transform into a stronger, unstable form
unleash devastating attacks
restore control by collecting healing elements
Use mutation wisely — it can save you… or consume you.

A WORLD THAT IS DYING
Traverse a living organism on the edge of collapse:
flowing vessels
immune zones
infected regions
Every area tells part of the story.
