Evaluation
Mysterious School (also known as "Haunted Schoolyard" / "Paranormal Campus") launched on February 16, 2023 and received a couple of early content updates in the days following launch. The game then went quiet until late 2024.
On November 12, 2024, the developer published a significant announcement explaining that player numbers had dropped sharply, making it hard for paying players to find matches. The studio announced it would make the game free-to-play within a week. Critically, the same post revealed that the original development team had fully disbanded — members had left for various reasons and were now working elsewhere across the country, making it "extremely difficult to regroup them to update the game."
Following the free-to-play transition, a flurry of updates arrived in December 2024: new playable characters, a third-person camera mode (in testing), private room functionality, microphone input options, lobby ping display, and various bug fixes. A developer note from December 4, 2024 also explicitly confirmed that content updates would continue to be free.
However, the last recorded developer communication was on December 22, 2024. There have been no posts, patches, or announcements since then — a silence of roughly six months as of June 21, 2026. Given the earlier admission that the core team had already disbanded, and with no updates since December 22, 2024, it is genuinely uncertain whether active development is continuing or whether the December 2024 burst represented the final effort from a skeleton crew.
Evidence
Bug fixes for character clipping exploit, first/third person camera switch, and teammate name visibility. This is the last recorded developer communication as of June 21, 2026.
Developer announced the game would become free-to-play within one week due to declining player counts. Critically disclosed that the entire original development team had disbanded and scattered, making future updates extremely difficult.

About this game
[Background Story]
In this town lies an abandoned school that has been deserted for years, after a tragic incident that occurred there. A beautiful young girl committed suicide inside the school, leaving many people deeply saddened by the news.However, strange occurrences started to happen in the school after that. Every night at midnight, an identical girl to the one who had committed suicide would appear in the school cafeteria. She would sit there for an hour before disappearing, leaving the same message every time: "I want to go home."
Even more mysterious, people would sometimes catch a glimpse of her in various corners of the school, only to have her disappear in the blink of an eye. Many students and teachers were afraid of these occurrences and didn't dare venture out at night.
Some believe that this is the girl's soul searching for the way home, seeking help rather than threatening anyone. Regardless, everyone in the school hopes that her soul can find its way home and rest in peace.
[Gameplay]
In this horror game, you need to work together with your team to find and destroy the evil items that manipulate the girl, in order to rescue her soul. Of course, if you are brave enough, you can also complete this task alone.The girl won't always be chasing you; her appearance is governed by different rules. There are five different talismans in the game, each with its own power. You need to observe the situation at all times because the rules change in different stages. Once you break the rules, you will be in big trouble.
The game not only includes the task of breaking the curse, but you can also find other interesting things around the campus. You can go to the basketball court to shoot some hoops, or use the basketball to scare the chickens. There's also a storage room that seems to contain some fireworks. See if you can find it and have a fireworks party with your friends in the schoolyard.
