CAHEM is a start-up of virtual reality amusement parks, having started its activity in Normandy. The franchise, designed as a scalable and turnkey model, was extended at the end of 2019 to the Paris Region with the opening of one of the largest centres in Europe. With its team of developers, CAHEM produces its own exclusive titles, available in single or multiplayer modes: shooter, role-playing game, arcade, or escape game. Most of the licenses are inspired by the myth of Cthulhu, the masterpiece and popular work of the writer H.P. Lovecraft. Believing in the development of esport in virtual reality, CAHEM is a permanent technological watch and calibrates its video games for this activity.
