RustyLake is a (mobile) game developer known for their series of Cube-escape games. With a big cult following around the world, the company wanted to create a special experience for their fans at their upcoming live-events. Interactive matter created two interactive artefacts, part of a mini-game that can be played at their live events.
One object is based on an old pay-phone, modded to play mysterious messages guiding visitors through the game. Visitors need to find a special coin and puzzle their way through to find the phone-number of the protagonist. After calling this number a distant voice reveals the next hint in the game.
The second object is a pedestal for an important game artefact, the black cube. Being known for their mystery and eeriness, this is not an ordinary pedestal; it includes various special effects to add to the multi-level experience.
