Players move their troops freely on a huge map and can change their attack target at any time. Players must set their strategies to besiege cities step by step in this all-out war event. In order to besiege the most cities and defend their own faction, they must mine numerous resources, gain the most buffs, and defeat powerful opponents. Unlike in previous castle siege events, players will not be able to enter and occupy cities until they have destroyed the city gates. Attacking players will be able to train troops in the military camp of the city closest to the front, drastically reducing march distance and time. If an enemy military camp is destroyed during a siege, the enemy will no longer be able to train troops in that city, further emphasizing the victory for the enemy.

This update also introduces a new "Chariot Vehicles" system exclusive to this event. Different types of vehicles have unique functions that can make the battle more unpredictable. Players choose between offensive, defensive, and logistical positions to help their faction gather resources and produce vehicles.

Thousands of players from different factions will be able to fight each other for glory on the same map! No matter which military position they choose, everyone can contribute to their faction's victory and enjoy the real-time strategy battlefields in Game of Thrones Winter is Coming.
