Beta 2026-2

Transferred from Frontiers' original host

The Beta releases were originally written and published on HackMD, Frontiers' first home, and were migrated here when the engine moved to its own site. Formatting, links, or images may occasionally show artifacts of that transfer. The rules text itself is preserved as released.

The current public iteration of the Frontiers Engine. This release is structurally complete at the engine level and is meant to be read, played, modified, and stress-tested.
