As soon as humanity had the means we sent out an interstellar colony ship. Its design was basic but elegant. And it made it all 40.7 light-years to Trappist-1.

— Ship data files

On arrival at Trappist-1 you control the Ark. A large spaceship/movable colony and trading hub for your exploration of Trappist-1.

Trappist is a story-driven colony builder with resource management in the Trappist-1 solar system, and a focus on care-free building and story.

It's easy to play and respectful of your time. You'll create and grow multiple colonies in the Trappist-1 solar system, meet new alien friends and explore the mysteries of Trappist.

Trappist is fully playable from beginning to end and is under active development with more stories, colonies and improvements coming.

Explore the Trappist-1 solar system

Fly through the Trappist-1 solar system and survey each planet to find the best locations for your colonies.

Discover and excavate alien artifacts hidden in the system and uncover the true purpose of Trappist-1.

Build your colonies

Build colonies on the planets and moons of Trappist-1. Each colony has distinct resources and buildings that are necessary for success.

Fill your cargo ships with the extracted resources and fly them to your manufacturing or population centers. Create automated trading routes for stable production chains across your colonies.

Fly your Ark as a mobile colony or place it strategically as your central trading hub.

Planned features and continued development

These are some of the features I hope to implement:

• More colonizable planets
  
• More aliens
  
• More research projects
  
• Improved models and sound effects

Trappist is under active development. But as a solo developer I can't guarantee everything will be implemented, or will be implemented to an extent you might want or expect. I recommend you consider purchasing this game based on its current state alone.
