Horizon Engine

Preview

Builds straight off the workbench and the devlogs behind them — weeks or months before any of it reaches a release.

Testers only

The Preview Program

Builds before release

The same editor we're working in today, for all three platforms — cut from the current branch instead of a tagged release.

Devlogs in progress

Feature write-ups that haven't been folded into a release yet, so you know what changed and what to look at.

Rough edges included

Unstable by definition: things break, formats change, projects from a preview build may not open in the next one.
