The Communication Playground01-Project represents an experimental game structure, where new communication strategies in the Internet can be tested in a game situation. The realisation basis is provided by the first-person shooter game `Quake III`. The idea is to create personal, demanding virtual realities in which individuals can meet and communicate via the Internet. The implementation of Avatars enables the individual to receive visual feedback from the chat partner in real time. In order to create an appropriate environment to experiment, a game was developed to promote and also provoke these requirements purposefully.
