The useful answer

The 1.0 release adds playable Tetramon, Workbench deck editing and Ascension packs. Check the official release post for your platform; old Early Access advice may no longer describe the same features.

What is new

The release post lists NPC card battles, participation in your hosted tournaments, Ascension packs with 1,452 new cards, and five new Steam achievements. It also describes performance work and card-text changes. For the steps to begin a match, use the first-duel guide.

Fixes appended to the release post

Build 1.01: the developer lists changes to graded-card opening, controller UI and joining tournament matches.

Build 1.02: the notes mention more likely Ascension gift packs after duel wins at lower shop levels, a duel-win achievement counting fix and a possible fix for tournament progress. “Possible” matters: the note does not establish that every stalled tournament is solved.

If something still does not work

Record your platform, installed build, the action immediately before the problem and whether mods are involved. Compare the symptom with the official notes. If you report it, give reproducible steps rather than just saying that the update is broken. Avoid deleting a save as an initial troubleshooting step.

Why release dates may look different

SteamDB records the Steam release timestamp as 14 September 2026 at 16:49:59 UTC. That is 15 September in China. The developer's announcement uses 15 September. The Early Access release is a separate 2024 date; it should not be confused with the full launch.

The version timeline so far

For anyone arriving late, here is where 1.0 sits in the game's history. Dates come from the developer's announcements (collected via a third-party archive of them); the Steam news page remains the authoritative record.

  • 6 August 2024 — the free Prologue launches on Steam, a free-to-play slice of the core loop that still exists separately today.
  • 2024 — Early Access launch of the full game; two years of patches follow.
  • 20 March 2026 — v0.70, the Tournament Update, adds hosted tournaments (NPC-simulated) and the camera app.
  • 23 April 2026 — v0.70.3, tournament bug fixes.
  • 15 September 2026 — v1.0: Early Access ends; playable Tetramon, the 1,452-card Ascension expansion, five new achievements and performance work. The 1.01 and 1.02 fixes above were appended to the release post in the days after launch.

The developer has stated that 1.0 is a milestone, not the end of development — so expect this timeline to keep growing, and old guides to keep aging. Community links for following along are on our resources page.
