Calyx Hold the line against the green

Build a fortified base on a hostile planet and fight back a spreading alien plant with tanks, flamethrowers and an orbital laser.

Screenshots

An enemy that grows while you build

The Calyx are not an army marching at you. They are a plant, and left alone it creeps across the map until whole regions belong to it. That changes how every mission plays: the vine is always spreading, so standing still means losing ground. You scan the Calyx roots to learn how the different varieties work, and new and more dangerous variants keep showing up as you fight for control of the planet. The pressure builds steadily until something gives, and it is usually on you to make sure that something is not your base.

Running the outpost

You are the last person left on an Avaris Corporation mining vessel, fresh out of a century in cryo, and the ship's out-of-date AI is your only company. It points you at Ore deposits and you get to work: drop Harvesters, refine Ore, ship it to orbit for Credits. Power is the real puzzle. Every turret, harvester and factory draws from the same network, and if the grid runs short, your defences go dark at the worst moment. Rare deposits and booster buildings are worth fighting over, since they improve your mining, military capacity and healing.

Building your war machine

Defend or attack early, dig in or stay mobile: the game lets you pick a style and develop it. Walls and turrets hold the line while you assemble a force, and the tech tree turns Research Points, earned by protecting Data Archives, into serious hardware. Unlock the Inferno flamethrower and watch the Calyx burn. Build the Unit Workshop and roll out the Goliath, a massive multi-turret tank that hover technology makes faster. And when the vine has spread too far, unlock Orbital tech and burn a swath of it away with a laser fired from orbit.
