Chthonian TD Leaves Early Access with Version 1.0

Chthonian TD has reached its 1.0 final release, departing Early Access as of July 9, 2026. The announcement, posted by author CGS, frames the update as a refinement rather than a reinvention — a set of targeted balance adjustments rather than sweeping new content.

What changed

  • Wave pacing has been adjusted for a smoother feel
  • Progression has been refined for greater clarity
  • Overall run consistency has been improved

The developer closed the announcement with thanks to players who supported the game during its Early Access period, suggesting the release marks the end of a community-driven development phase rather than the beginning of a new content roadmap.

For players already familiar with Chthonian TD, the 1.0 release signals a stable, finished baseline — the version the developers consider the definitive expression of the game.
