What the developers have to say:

Why Early Access?

“We’ve always wanted to bring players into the world of Core Keeper early to help shape the game and make the best experience possible. We know that listening to players during development will help make Core Keeper an even better game, and plan to add new content, test new features, listen to player feedback and refine the game experience throughout Early Access.”

Approximately how long will this game be in Early Access?

“It’s important to us that we remain flexible and respond to players' thoughts and feedback, which may have an impact on our development roadmap. Our goal will always be to make the best game possible.”

How is the full version planned to differ from the Early Access version?

“We’ve already been working on Core Keeper for almost a year and feel like the Early Access version is at a great point in development for players to begin the adventure and start playing. But there is still much more to come and we’re planning to add many more features and content throughout Early Access, including:

  • New biomes, enemies and bosses.
  • Many more items to find and craft.
  • Additional story elements, including the second stage to unraveling the mystery of the Core (and an ending!).
  • Additional gameplay mechanics for cooking, farming, smithing and base building.
  • Tweaked & refined game design iterated on through community feedback.
  • Additional language support.

Of course, these are just some of the things on our roadmap right now, and we are keen to keep community feedback in mind throughout development. For example, Early Access will launch with support for up to 8-player multiplayer and we’re interested to see how players respond and work together, which may have an impact on the final multiplayer aspect to the game.”

What is the current state of the Early Access version?

“We plan to update the Early Access version regularly with new features and content, but right now the Early Access version contains:

  • Gameplay content from start to early/mid-game.
  • Single player and multiplayer support.
  • An endless procedurally generated world with different biomes.
  • Lots of creatures and three massive bosses.
  • Over 140 items to find or craft.
  • Base building, smithing, farming and cooking.
  • Equipment and skills systems.
  • Melee and ranged combat.
  • The first stage of revealing the mystery of the Core.
  • Keyboard & Mouse / Controller support.

Will the game be priced differently during and after Early Access?

“We expect the price to increase as we transition out of Early Access and into full release, due to the final game having more content and being a more stable, rounded experience.”

How are you planning on involving the Community in your development process?

“We’re planning to listen very closely to what the community is saying throughout development, taking players’ comments and feedback onboard to help us refine the game, prioritise content and develop new features. As well as listening to player feedback on the Steam forums and social media, we would love our Early Access players to join our Discord, where we will have dedicated feedback channels for bug reports and suggestions from the community. We’re really keen for players to get started on their adventure and listen to what they have to say.”
