Mahasona is a multiplayer game with elements of horror and social psychology. Here, 4 comrades suddenly discover a strong enemy who is not going to spare anyone and is ready to destroy anyone who interferes with the achievement of his goals. He has already begun his hunt and it is difficult to predict who his next victim will be, so getting together in a group may not be the best idea.

Mahasona is a demon who guards underground passages leading to treasures. For everyone, these stories were just a stupid legend and horror story that kept even curious children from exploring the dangerous underground corridors, where it was easy to get lost or even fall into a collapse. But a group of friends still decided to disobey the ban and go in search of the promised riches. To open the way to them, they must first find 4 artifacts, but after wandering around the place a little, they did not expect that they would meet a huge angry monster from fairy tales, who fiercely attacked them in order to destroy the troublemakers.

In Mahasona, 5 users who know each other or are randomly selected can take part in rounds. 4 of them received the roles of ordinary people and the fifth will be randomly chosen as a demon who will need to track down the kids and eliminate them. The round is considered over when the monster eliminates everyone from the group of friends or when they find and collect the treasure.
