What the developers have to say:

Why Early Access?

“To fully design the game we want to build, we need your input. There are not many games in this genre and we want to adapt to your needs as much as possible. ”

Approximately how long will this game be in Early Access?

“We currently aim to release the full version in Q1 2027. This may change based on the input players provide.”

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

“The full version is planned to include a variety of theme park rides as well as park management features. Terraforming and procedurally generated planets will enable a more personalized experience. Share your rollercoasters and parks via Steam Workshop with other players.”

What is the current state of the Early Access version?

“At this moment, the Early Access version includes a variety of roller coasters and tracks that enable the player to build their own roller coasters in space. Choose from many customizable decorations to add something extra to your theme park.”

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

“The price will increase when Early Access ends.”

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

“You are invited to join our Discord linked on the right side to connect with the developer and share your ideas and feedback.”

About This Game

Build. Ride. Defy Gravity.

Welcome to Coasteroid! The space-faring roller coaster builder where you design the most outrageous rides in the universe.
Construct twisting tracks across landscapes you have not seen before, loop through asteroid craters, tunnel through planets, and launch straight into orbit. There are no limits here; break the physics!

🎢 Key Features (Early Access)

  • 7 unique coaster types – each with distinct track styles, speeds, and behaviors.

  • Multiple planets to build on – can you build in different gravity and terrain?

  • Unlimited coaster creativity – twist, flip, and stretch tracks in any direction you imagine.

  • Special tracks – launch riders off the rails with zero-gravity jumps and wild transitions.

  • Decorate your dream park – choose from themed sets or fully customize your own decorations and color palettes.

  • Planet tunneling – dig straight through the crust to connect your rides or hide secret routes underground.

  • Ride your creations – switch to first-person view and experience every drop, twist, and loop yourself.

🚀 Coming in the Full Version

  • Park management and guest simulation.

  • A full range of rides beyond coasters.

  • Terraforming tools and procedurally generated planets.
