Steam post image

There are lots of new things to try out, including:

  • 6 new Challenge maps.

  • Events system - for example, a sandstorm that reduces solar power and weapon range.

  • Calyx species get even stronger, and lash out when attacked.

  • Build the Unit Workshop to unlock unit upgrades.

  • Formation types: select different shapes for groups of units. Use Shift to flip them 180 degrees.

  • Zeus Cannon unit. It’s a big laser tank!

  • Ore Thumper building. Makes an Ore patch regenerate faster, but uses a lot of power.

  • Flamethrower Turrets. A fiery new variant for your defences.

  • Show attack ranges of all objects by pressing R.

We also added some new settings:

  • Disable chromatic aberration.

  • Change the autosave interval.

  • Adjust volume of voices separately.

Plus there are many smaller tweaks, balancing and polish items.

Thanks and we hope you enjoy!
