From an abandoned mountain fortress you command a group of Norwegian volunteers fighting numerically superior German forces in the early days of WW2.

Halls of Hegra is a solo only game in the same vein as Robinson Crusoe, This War of Mine and Dead of Winter. The mechanics are worker placement, bag building and area control / tower defense.

Play as the commander of the Norwegian forces. Explore the fortress and dig your way through mountains of snow and broken equipment. New recruits are joining while you plan supply routes for the coming siege.

Defend the village below the fortress while you do the final preparations before the Siege. Send out patrols behind enemy lines to secure enough supplies.

During the Siege you have to endure constant bombing and infantry attack while keeping the morale up amongst your men. Will you survive?

Event Phase: Events are resolved and you are attacked by the enemy.

Morning Phase: Supplies are divided among your defenders. Place defenders on the different action spaces.

Day Phase: Each action space is resolved in numerical order.

Morale: At the end of the day, morale and surrender checks are made. The current morale level is resolved. If you survive, you continue to the next day.
