The game Counter-strike is about organising in Teams of 2-5. It is a TERROR VS. ANTI TERROR game. It is probably the most popular computer game at the moment especially among youngsters. At Rooseum there is free admission if you are under 16 years old.
Along with the game there is a cinema / video archive with documentaries and fiction films about social and political change, where people have organised themselves collectively in order to achieve their aims. There is currently a collection of 20 different films in the cinema. While not playing the game you can watch a movie from the video archive.
