Evaluation

School 666 launched on June 11, 2025 after two delays, and the developer followed up with a rapid series of patches through June 28, 2025, addressing multiplayer bugs, balancing, and quality-of-life items. On June 16, 2025, the developer posted plans to add a Hard Mode with randomized anomalies and 6 new harder anomalies per room, framing it as something they were considering based on player feedback and asking the community for their thoughts. That June 16, 2025 announcement is the only indication of planned content beyond launch. However, it is framed as a proposal or plan under consideration ("I plan to add…", "let me know what you think"), not a confirmed commitment with a roadmap or release date attached. No further news posts, DLC listings, or developer statements have followed since June 28, 2025 — over 14 months of silence as of today, September 24, 2026. There are no unreleased DLC entries on the store. The developer has not reaffirmed the Hard Mode plan, and there is no established post-launch major content cadence to suggest more is coming — the game's single major content event was its June 11, 2025 launch, with only bug fixes and a feature patch in the weeks that followed. Given the length of silence since the last communication on June 28, 2025, the absence of any confirmed content commitment, and no unreleased DLC on the store, the game is best assessed as complete. The Hard Mode mention was a community-facing proposal, not a formal announcement, and its non-delivery over 14 months of silence suggests it did not move forward. The last developer communication and the final patch date of June 28, 2025 mark the practical end of active post-launch work.
