Watch the trailer

Meridian engineers and cranes work at a wrecked landing site in a dark fungal forest. A crystal spire of light stands in a ring on a snowy plain under the stars. A huge red heart of living flesh pulses in a black swamp, with violet veins spreading across the ground.

The world

An empty frontier

Leukosia was supposed to be empty. The Meridian Hegemony came for its fungus fields and salvage.

They were not alone

The Vaelori came too. They've seen this before, and they mean to stop it ending the same way.

Then the world woke

The planet itself began to answer back. It has an immune system, and you are the infection.

Three races. One world. No retreat.

Each race plays differently. Pick one and learn how it wins.
