Whiteout Survival Fortress Battle
Fortress Battle in Whiteout Survival is a weekly alliance contest for Fortresses and Strongholds, with occupation adding points across an 8-week season. Register a target, defeat its defenders and hold it under the event's control rule to secure the result. Sunfire Castle has a separate battle cycle and presidency reward, so it needs its own timing and objective plan. Checked in November 2026.
Fortresses and Strongholds
The world map has 12 Fortresses and 4 Strongholds for this competition. Each successful Fortress occupation adds 1 season point, while a Stronghold adds 2. Use those point values to compare season progress, and inspect each building's reward preview for its items.
| Target | Buildings on map | Season points per occupation |
|---|---|---|
| Fortress | 12 | 1 |
| Stronghold | 4 | 2 |
Targets captured in the previous battle are automatically registered for the next one. Leadership should review that inherited list before choosing an additional target. The current sign-up panel determines how many new selections are available, so count the displayed registrations instead of assuming the same new-target limit in every run.
First-season Strongholds begin around four weeks into the season. The State Monument's Fortress milestone opens the system, with R4 and higher handling registration. If your alliance is still early in its state timeline, check the milestone and target window before planning a Stronghold rally.
For passive world-map bonuses, use the separate Facilities reference. For the people responsible for sign-up and reward allocation, see alliance officer roles. Those systems support the plan without changing a Fortress into another building type.
Schedule and Control Timers
The weekly battle is listed on Friday. Officers select 3 preferred time slots during sign-up, then the target window supplies the actual battle time. Confirm the displayed UTC slot with the members assigned to attend rather than treating a preferred choice as the final appointment.
The Fortress battle window can be between 1 and 2 hours, with a continuous-control condition around 30 minutes. Read the target's live countdown for the exact finish condition. Taking the building once is the beginning of the hold, not a substitute for completing that timer.
The sequence runs through Sign-Up Stage, Battle Stage and Defense Phase. Before battle, check the registered targets and the members who can attend. During combat, track the building owner and control progress. After occupation is secured, review the reward categories rather than assuming every item uses the same distribution rule.
A rally or solo attack can capture a target. For a contested building, coordinate the target assignment in chat before sending your march. Keep watching its owner and occupation progress, because the opening defender clear and the completed control timer are different parts of securing the building.
Attack and Defense Preparation
Guides suggest an attacking starting split of 50% Infantry, 20% Lancer and 30% Marksman. Defensive examples use 60/30/10 or 60/40/0. These are suggested formations for different jobs, rather than automatic replacements for an officer's assigned march.
Jessie is an attack-joiner recommendation, with Jeronimo listed as a premium leader option. Sergey and Patrick are defensive recommendations. Check your intended role before selecting the first hero, and compare the suggested heroes with your actual roster through the PvP hero overview.
The troop ratio explanation covers the class split. Keep it separate from the holding timer: a formation helps you prepare for combat, while occupation determines whether the target is secured. Both need attention, and a successful opening attack does not remove the defensive part of the job.
The video from the game's Beginner's Book series shows the rule for holding a fortress, basic rally rules and two ways to take one, including a double rally.
Capture and Season Rewards
The alliance's initial capture produces alliance and allocatable rewards alongside the opening participation payout. These are separate categories with their own conditions. Check the category in the reward preview before comparing mail with another member, and distinguish an initial capture payout from the points earned toward the season ladder.
Season points accumulate from occupied Fortresses and Strongholds. Compare the live season total with the current season reward ladder; the point values in the table do not mean that every target has an identical item payout. Hero-shard rewards also depend on state progression, with generation-two shards becoming available once the state reaches generation four.
Avoid choosing a target only because its name sounds more valuable. Strongholds give more season points per occupation, while the building preview shows the reward items for that target. Discuss both the season goal and the current item rewards when officers choose where the alliance will commit its available members.
Sunfire Castle Battle
Sunfire Castle follows a separate 2-week cycle. Domestic Castle Battle is fought within the state, while the SvS version brings a rival state into the contest. In SvS, the preparation loser hosts the Castle Battle. The full preparation cycle belongs in the State of Power guide.
The Castle Battle window runs between 5 and 6 hours. Continuous occupation can require between 2.5 and 3 hours; use the current castle panel for your event's timer. If no alliance meets continuous occupation, the longest total occupation time decides the winner.
Turrets controlled by an enemy alliance damage the castle occupants. Longer turret control shortens the interval between attacks. This makes turret ownership relevant to holding the castle, rather than a side objective disconnected from its defenders. Officers can assign different members to the castle and the surrounding turrets.
The Alert Zone storm moves cities to random positions 2 hours before the event. Account for that movement when choosing a position and discussing arrival with the alliance. Guides also recommend closely coordinated rallies to reduce the defending alliance's time to reinforce between attacks.
Presidency and Ministers
The winning alliance has 10 hours to appoint the President. This leadership result belongs to Sunfire Castle, while ordinary Fortress and Stronghold occupations contribute to the separate season ladder. Knowing which event you are preparing for prevents a weekly target plan from being confused with a presidency contest.
The administration has 6 minister positions: Vice President, Minister of the Interior, Minister of Health, Minister of Defense, Minister of Strategy, Minister of Education. Their effects serve different development tasks. The Minister of Health offers +100% Healing Speed and +5000 Infirmary Capacity; the Minister of Education offers +50% Training Speed and +200 Training Capacity.
Castle personal scoring has Carnage, Occupation and Casualty Points. Keep those personal categories distinct from castle ownership time and from the weekly Fortress season points. They describe different parts of the event result and should not be added together as if they were one shared currency.
Frequently Asked Questions
Can I change alliances on Fortress Battle day?
Participation uses your alliance membership at 00:00 UTC on battle day. Rejoining your original alliance that day is permitted, but joining a new alliance does not let you fight for it immediately. Arrange a planned move around that cutoff instead of relying on a new alliance invitation just before the target opens.
Can officers give every distributable reward to one member?
No. R4 and R5 officers allocate those rewards, but individual limits apply. Participation rewards, alliance rewards and the distributable pool have different conditions, so check which category you are discussing before assuming the same allocation rule covers every item received after a capture.
Are Fortresses the same as Facilities?
Facilities provide passive alliance buffs, while Fortress Battles are the weekly contests for Fortresses and Strongholds. The names refer to different world-map systems. Check the building label before following a capture plan, especially when alliance chat uses an informal abbreviation that could refer to more than one target.
Can I receive rewards by attacking the opening defenders alone?
A solo attack can receive the opening participation reward for the attacker, while a rally includes its participating members. Guides therefore recommend a rally for the initial NPC clear when the alliance wants more members involved in that reward. This opening participation payout is separate from the later occupation result.
Who becomes President if no appointment is made?
The winning Alliance Leader becomes President when no appointment is made within the 10-hour deadline. An existing President in the winning alliance may be re-elected. This belongs to the Sunfire Castle result, rather than the ordinary weekly Fortress season score, so keep the two reward systems separate when planning leadership duties.
