New features – sneak preview
Bastion
Calyxa Castellum
This tough new Calyx rains down fire on any unit that strays into range.

Militia
Calyxa Militum
This new species spawns creatures which attack your units and base.

Tormentor
Calyxa Tormenta
The pink Calyx now has a proper name and more sophisticated behaviour. You can also see the new Orbital Laser weapon being used to take out a trunk.

Razorleaf
Calyxa Propagare
Our old friend the green Calyx is also more advanced, growing additional nodules and levelling up in strength over time.

Harvesters
We’ve added a Harvester based mining system with a new Refinery building to collect that sweet Ore.

Player survey
We’ll be creating a short survey so you can give feedback on the new features. There will be a link to the survey from within the playtest build.
Thanks for your support!
More than 50,000 players have now installed the Calyx Demo, which frankly blows our minds. We can’t wait to hear what you think of the new additions.
Thanks!
