Calyx (PC) Steam Gift Global

Dig in and power up

A hybrid RTS and base-building strategy game featuring a terrifying new kind of enemy: the Calyx - aggressive plant-aliens that spread relentlessly across the map if left unchecked.

You are the last surviving crew member of an Avaris Corporation deep-space mining vessel. After more than a century in cryosleep, you’re abruptly dropped onto the surface of a barren planet while the ship’s AI calmly assigns you mining quotas.

The planet isn’t empty.

Construct a sprawling power network, deploy Harvesters, refine Ore, and launch it back into orbit for Credits. Every structure draws energy - mismanage your grid, and vital defenses may shut down at the worst possible moment.

Fortify your base with walls, turrets, and artillery, then deploy tanks and mobile units to push back the ever-growing Calyx infestation.

Power communication arrays to access Avaris Corporation’s deep-space network. Scan Calyx roots to study their biology. Discover new variants as you fight for control of the planet - and search for a way home.
