It is about a castle that has to be conquered or defended in several game modes.
The castle has special features. Doors require keys or can be controlled centrally, there are cameras, a large surveillance monitor and power management. Some of these things can be upgraded during the game.
Attackers can get into the castle by digging their way in, scaling the wall with a siege tower, blowing up the castle gate or taking a key from a defender (by killing them).

Conquest is currently the only playable game mode. It is about capturing and holding flags in the castle. If the attackers hold more than half of the flags for 5 minutes, they win. The defenders win if the attackers do not manage to capture the castle within 30 minutes.
