The Tunnels is a psychological thriller written by Jerker Virdborg for the podcast P3 Serie. It takes place in the underground tunnels of Stockholm and tells the story of how a man’s increasing obsession with the underworld has fatal consequences.
To market the show, we created an interactive trailer on Instagram, where the visitor has to get down in Stockholm’s tunnel system and navigate through different tag-functions, picture carouselles, sounds and films. On the most difficult levels, the player had to leave Instagram and search for further clues on the Internet, make a few phone calls and listen to voice messages. The first ten people who completed the game won a guided tour in an old nuclear power plant deep below The Royal Institute of Technology in Stockholm.

The campaign started with a sponsored Instagram story from P3 Serie and standard film ads on InstagraM.
The first level starts on the streets of Stockholm. You, the player, have to find out how to get down into the underground. Once inside a parking garage underneath a church you need to find the right door to get further down underground. It all gets a bit creepier and darker as you try to find your way forward. Since the urban exploring community is built on personal trust and knowledge you will need to reach out to others to get all the way to the end of the game. Good luck. See you down in the tunnels.
