Evaluation

Afterbeat (formerly Project Arrhythmia) launched its 1.0 release on October 8, 2026, graduating from a long Early Access period. The developer confirmed the release date on August 19, 2026, and the launch post on October 8, 2026 announces the full game is now available, featuring a Complete Story Mode with 20+ hand-crafted levels, local co-op for up to 4 players, and a robust level editor with a large community of user-created content.\n\nThe game launched today, and the developer has made no statements about post-launch content plans. The single released DLC is the game's soundtrack, which shipped in July 2019. There are no unreleased DLC listings and no announced roadmap for additional content after 1.0. Given that launch just occurred, it is simply too early to determine whether the developer intends to continue adding content beyond the 1.0 release.
