Evaluation

Knockout Master is a completed visual novel. The developer, MooN, explicitly announced on May 1, 2025 that Round 14 would be the final update, stating "Round 14 is finally complete, and with it, Knockout Master comes to an end." The May 2, 2025 release post confirmed this, labeling the update "v1.14 Final" and presenting a full cumulative changelog representing the complete game (Season 1: Rounds 1–9, Season 2: Rounds 10–14, 17,000+ renders, 850+ animations, 83 achievements, multiple endings). The developer also confirmed they had met their own self-imposed goal of finishing the game by mid-2025. Following the completion of the main game, MooN continued post-launch support in the form of translation work — adding 8 languages in December 2025 and 3 more in January 2026 — but these were localization updates, not new story content. In that January 2026 post, the developer also linked to the Steam wishlist page for the already-announced sequel, Knockout Master 2, confirming the original game is fully complete and the team has moved on to the next project. No new content for the original game has been announced or is expected.
