Visit the Calyx Steam Page, scroll down and hit the “Request Access” button.

When the playtest is available we’ll publish another news post to let everyone know.

• Challenge Mode with 5 new maps.
  
• New types of Calyx.
  
• Existing Calyx are more sophisticated.
  
• Targeting system revised.
  
• New player unit types.
  
• Harvester based mining.
  
• Draw walls and pylons.
  
• New resource - Isotopes.
  
• Harvest, Healing & Power Boost Modules.
  
• Lots of new QOL features including re-bindable keys.

This tough new Calyx rains down fire on any unit that strays into range.

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

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.

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

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

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.

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!

We’re delighted to say that more than 35,000 of you have now added the Calyx Demo to your library, since we first launched it for Steam’s RTS Fest on January 20th.

Thanks for all your detailed suggestions and feedback. We spent time reading and digesting your contributions, and combining them with our own.

It’s now time to give you a quick update on what we’re planning next.

It’s our intention to share a bigger slice of the game with you, and we’re aiming for around the middle of 2025 for the demo update.

• Updated targeting system for player units
  
• New types of Calyx plant
  
• New units (including plant units that make defenses far more important)
  
• A new resource
  
• A new mining system based on harvesters (no more trying to place mines to clear up every last scrap of ore)
  
• Existing modules and buildings in the world - connect to these for boosts
  
• More maps
  
• Lots of QOL features including more options and keyboard shortcuts
  
• Many smaller improvements

We hope that gives you a good idea of where Calyx is going next.

We’d like to say a huge thanks to everyone who’s played, reviewed and wishlisted so far. We’re stoked so many of you see potential in the project!

Stay tuned for another update soon.

Cheers!
