Eavesdropping scandals, stolen data, encrypted messages - all of this is included in Data Run. In this so-called alternative reality game, which involves roleplay, schoolchildren slip into the role of hackers and with the help of an investigative journalist expose a double agent and thus prevent an attack on Berlin. In the realistically designed conspiracy thriller, they search for passwords and work with encrypting software, thus engaging playfully with issues such as mass surveillance and data privacy. Data Run can be downloaded free of charge and can be developed further.
