What it is

4XCiv is a real-physics civilization sim. Every planet, moon and asteroid is rendered from real mission data, from HiRISE to New Horizons, all the way down to the ground. 4XCiv Explore puts the whole solar system in your browser, free and with no login.

4XCiv Play is the 4X game on top of it: survey hex plots, build a colony, craft from a 173-item catalog, fly real transfer windows and fight under real gravity. Play is in crew testing.

Where Bike4Mind fits

The game's AI runs through Bike4Mind: the engine talks to the Bike4Mind API through a streaming proxy, and its in-game captains and GameMaster are built on it. The agentic AI officers at the centre of the design are partly still in development.
