Basic Rules
The main goal of the battleground is the fighting and occupying of strongholds, which will provide Alliance points continuously once occupied. When the battleground ends, the Alliance with the highest amount of points will win.
Troops will automatically occupy and garrison an unoccupied stronghold upon arrival.
Troops will automatically initiate combat if the stronghold has enemies garrisoned within. All garrisoned troops must be defeated to occupy the stronghold.
Upon occupation, strongholds will enter a "Contested" status. Troops must maintain control over the stronghold for a certain amount of time to successfully occupy it. If it is the first time the stronghold has been occupied, then the occupying Alliance will receive additional Alliance points and Personal points
After successfully occupying a stronghold, most strongholds will provide Alliance points every minute, up until the stronghold is occupied by an enemy or the battleground ends. Thus, occupying as many strongholds as possible is the key to victory.

Territory and Teleporting
Bases can only teleport to allied territory during the battleground. The territory in front of the Headquarters will act as a starting area for allied forces. Territory can be expanded by building "Watchtowers".
Watchtowers can be constructed by the Alliance Leader or R4 members by pressing on an empty tile. Construction of Watchtowers requires the resource "Meteorite," which can be gathered by locating and gathering "Craters," a special gathering plot in the battleground. Meteorite is shared between the entire Alliance.
A relative amount of Personal points and Alliance points can be gained from gathering Meteorite
Watchtowers require some time to be built. Each Commander can dispatch up to one formation of troops to speed up the construction. Once the Watchtower is completed, the territory around the Watchtower will become allied territory. Territory gained from building a Watchtower must connect with allied territory, or the Watchtower will be unavailable for construction.
During the battleground, teleporting will not consume any items, but will instead deduct from the Alliance Teleports, which is shared among the entire Alliance. At the start of the battleground, each Alliance will have 5 Teleports. Occupying the "Command Center" strongholds will provide additional Teleports.
Other than providing a tile to teleport to, the Alliance will receive points at regular intervals based on the size of allied territory.

Territory Conquest
Watchtowers can be attacked, and when its durability is reduced to 0, it will be permanently destroyed. When a Watchtower is destroyed, the territory it provided will be lost as well. Territories that lose connection to your Alliance's Headquarters will be put into a disabled status (shown as white). Constructing Watchtowers and connecting the disabled territories to the Alliance's Headquarters will restore function to the territories.
White unoccupied territories are in a neutral state. Both sides can capture the unoccupied territory by connecting their territory to the white unoccupied territory.
Losing a territory that has an existing Base will only disable the Teleport action for that Base.

Gaining Personal Points
The following are ways to obtain Personal Points during the battleground:
1. Occupy a stronghold for the first time
2. Gather Meteorite from a Crater
3. Fight an enemy and gain points based on the amount of Combat Power they lose
4. Successfully escort the Aerospace Key

Obstacle Rules
Obstacles such as mountains are dispersed across the entire map of the battleground. If a destination requires crossing over such obstacles, the marching route will automatically reroute around the obstacle and increase marching time accordingly.

Battle Phase (Operation: Oblivion)
The battleground strongholds will be available in 3 different phases:
1. Fortresses, Outposts, and Command Centers will be available at the start of the battleground.
2. Hospitals, Armories, and Rocket Repair Shops will be available in the 2nd Phase
3. The Spaceport and Relays will be available in the 3rd Phase.
Unavailable strongholds cannot be occupied. Pressing on an unavailable stronghold will display the remaining time to the next phase. Once the next phase starts, an announcement will be broadcasted across the entire battleground.

Participation Reward
Rewards will be sent by mail immediately after the battleground ends. There are three types of rewards total:
1. Alliance Reward: All members of the Alliance will receive this reward. Contents of the reward will be based on the Alliance's outcome in the battleground.
2. Mobilization Reward: Only for members who participated in the battleground. Contents of the reward will be based on the Alliance's outcome in the battleground.
3. Score Reward: Only for members who participated in the battleground. Different grades of rewards will be based on personal score. The higher the personal score, the better the rewards. The outcome of the Alliance in the battleground will also affect the contents of the reward.
