Greetings Calyx players!

Our playtest for version 2 of the Calyx Demo is now open.

If you already requested access, you should now have the "Calyx Playtest" product in your Steam Library.

To request access now, visit the main Calyx Steam page and hit the button under “Join the Calyx playtest”.

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.

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.

We’re excited to hear what you think, and it would be super helpful if (once you’ve played) you could fill out our playtest questionnaire.

We hope you enjoy it.

Thanks!

John, Mark & Phil ːsteamhappyː Studio 568
