In Valve many different larp techniques were tested, with varying degrees of success. There were for instance live sound design, scuba diving, theatrical experiments, modern dance, fireworks and van kidnappings. The campaign was played in various surroundings at Helsinki, including museums, galleries, streets, parks, private apartments and office buildings. The 10-meter dragon built in an abandoned railway tunnel was noted by the street art community [http://www.woostercollective.com/post/the-dragon-in-the-helsinki-railway-tunnel The Wooster Collective], which included it to its blog. The campaign was documented extensively with video and photography and so far one short film apart from the introduction video has been completed from the material.
