About the event

What kind of airsoft game is Battlegroup?

At Battlegroup, you are part of a larger force and its shared game. Faction commanders assign missions that infantry, reconnaissance teams and mechanised units carry out together at squad, platoon, company and battalion level. Players’ decisions shape how the action and the story develop.

The event combines MILSIM (Military Simulation) with elements of LARP (Live Action Role Play). You decide how deeply you want to immerse yourself in the game world. Both newcomers and experienced players are welcome.

Alongside the fighting, the game includes long movements, reconnaissance and everyday life at the base. Sometimes you wait for orders or maintain your equipment; at other times you head out on a new mission. Civilian characters and encounters bring role-playing and events beyond the battles.

The game lasts over 60 hours, so plan for rest, food and drinking water before you arrive. Most players stay at their faction’s base, where they maintain equipment and prepare for their next missions. Be ready for changeable weather and long days in the forest.

Because the game is demanding, the age limit is 18. Players aged 16–17 may apply for special permission to attend with adult players. Send a free-form application to info@ehasa.org.

Missions & story

Game control acts as the brigade and gives objectives and missions to the battalions. Each battalion commander assigns them to their troops.

Other in-game characters may offer optional side missions. Completing side missions has an impact on the game. We aim to publish game control’s major missions on status.ehasa.org so that the whole faction can see them.

Accommodation

Players sleep in their own tents at the bases, or elsewhere by prior agreement with game control. Reconnaissance platoon players may also camp anywhere in the game area.

Keep your eye protection on when sleeping in the game area or an in-game base.
