🇸🇪 Sweden
Sweden’s legendary MILSIM that mixes airsoft with LARP – military factions, civilians, gangs and traders, airstrikes, bunkers and airsoft tanks across a huge game area.
Berget is run by the company Berget-Events and is one of the longest-running large MILSIMs in Europe. Berget 5 on the island of Hemsö in 2007 brought 2,000 players together – at the time the largest airsoft meeting in Europe. Berget 22 (2026), ‘Operation Fort Knox’, returned to a much-loved game area near Sollefteå with a good road network close to the city.
Participants are placed in big teams with a military structure and overall objectives. LARP and civilian roles – soldiers, traders, gangsters and politicians – drive the story, and armoured airsoft vehicles (BAVs), airstrikes, bunkers and convoy attacks are part of the game. The organisers warn that the area is big and demanding: expect to walk long distances and read the full rules and beginners’ guide first.
Sollefteå, Västernorrland is about 2,310 km from Sofia as the crow flies. Most players fly and rent a vehicle for the gear – check the organiser’s rules on transporting replicas before you travel. Always check the organiser’s rules on replica transport, FPS/joule limits and tickets on the official channels before you book.
