Greetings Calyx players!

We’re excited to announce that version 2 of the Calyx Demo is now live!

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

  • Challenge Mode with 5 new maps.

  • New Calyx plants with new mechanics - watch out for the crawlers!

  • Existing Calyx species have been upgraded.

  • Calyx now level up - they get stronger the longer they're alive.

  • New player units.

  • Harvester based mining system.

  • New resource - Isotopes!

  • Boost Modules in the world - connect these to power for a bonus.

  • "Drawable" walls and pylons.

  • Re-bindable keys, adjustable UI scaling, and lots more QOL features.

  • Original music from our long time collaborator Gavin Harrison.

  • Now localised into Simplified Chinese, French, German, Italian, Japanese, Korean, Portuguese (Brazil), Russian and Spanish (Spain).

The tutorial has been updated with the major new systems, so that's a good place to start if you're new to Calyx or a seasoned pro.

Thanks and we hope you enjoy it!
