About This Game

"Mysterious School" is a horror game that supports multi player online and single player. Why do girls often cry on campus at midnight? What happened to the once famous No.1 middle school? Take your partner, find out the truth that the young girl has become a zombie, and help the girl reincarnate.

Detailed Description

[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.

[Game Features]

  • Fun hide-and-seek gameplay
Players need to be aware of the changing rules and avoid traps set by their teammates, using different strategies and plans to evade the pursuit of evil ghosts. Besides hiding, players can also use the environment to cover themselves, increasing their chances of survival.

  • Random paranormal events
Random and creepy paranormal events can occur in the game, such as encountering a funeral procession in a dark hallway, experiencing eerie illusions in the infirmary, or being trapped in a locked room, increasing the excitement of the game.

  • Huge map
The game map includes a complete school environment, including various classrooms, laboratories, infirmaries, offices, cafeterias, dormitories, security rooms, and basketball courts, allowing players to experience the game in a realistic setting.

  • Multiplayer experience
The game can be played by multiple people simultaneously, with players able to form teams to solve puzzles or play independently and freely explore the entire school.

  • Rich storyline
The background story of the game is captivating, with the main characters needing to unravel the story behind it and uncover clues to break the curse.
