Deploy tanks and artillery to push the Calyx back before it gets too strong. Balance your base’s energy requirements carefully to avoid vital defences being down on power. Secure rare deposits to improve your mining and military capacity. Connect to booster buildings for additional power, mining and healing buffs.

There are many ways to defeat the different varieties of Calyx. Start your base wherever you like, experiment and develop your styles of play, and learn to cope with different scenarios. Protect Data Archives to gain Research Points, and use the tech tree to unlock and upgrade more advanced units and buildings. Unlock the Inferno flamethrower and watch the Calyx burn! Build the Unit Workshop and manufacture the Goliath, a massive, multi turret tank, and boost its speed with hover technology. Unlock Orbital t...
