Players put on virtual reality headsets and dive, for one hour, in another dimension. They can see their hands, they can see each other, they can converse and exchange gestures, touch objects, shoot with the laser and fly in zero gravity. Some people experience discomfort during the first few minutes of play in the virtual reality environment. This is something strictly individual and manifests itself only in 10% of the players. If this occurs, the player must remove the helmet during 1-2 minutes, rest and drink water. In general, this does not affect the game sessions.
