In the fall of 2011, the Mölndal City Museum launched the digital adventure game Fylgja, which was based on the Tidsresan project and supported by the Torsten Söderberg Foundation. The aim of the game was to bring ancient worlds to life through experiential learning. Players are taken on an adventure through the Bronze Age and the Iron Age. The story begins at two existing archaeological sites, and all material featured in the game is based on thorough research, with museums, archaeologists, and experts from across the Nordic region contributing their expertise and materials.

The game was developed for Mac and PC computers and has been widely used in schools since its launch. Fylgia continues to attract an audience and is requested by schools as well as other museums in the country. However, technological developments have meant that the game is no longer adapted to either tablets or touchscreens, so its use is slowly declining. Therefore, the game now needs to be translated into the tools used today through reprogramming. Fylgia will then be available for download as an app in the App-Store. The purpose of the project Tidsresan 3: Fylgia for the future is thus to secure the solid work that has been done in the Tidsresan project and make the Fylgia game ready to accompany the digital journey for several years to come.
