Foundry Battle is a large-scale alliance vs alliance PvP event in Whiteout Survival, run roughly every two weeks. Two alliances fight to control industrial buildings and bank Arsenal Points — and because troops don't die, it rewards aggression. This guide breaks down the schedule, the three phases, the scoring, and how to win.

What Is Foundry Battle?

Foundry Battle pits two alliances against each other to capture and hold buildings for points. Eligibility is competitive: the top 20 alliances on the Alliance Power Leaderboard before the event qualify. A key mechanic sets it apart from most PvP:

💡 Troops don't die in Foundry Battle. Casualties are automatically healed at the end of the battle, so you can attack aggressively without losing your army. Trade hits freely and keep pressure on objectives.

Foundry Battle Schedule

Foundry Battle runs about every two weeks, with lead-in phases before the fight:

Phase	Duration
Voting	2 days
Registration	2 days
Matchmaking	2 days
Battle	~1 hour

During the battle, contested buildings open in three 15-minute phases.

The Three Building Phases

Phase	Buildings Available
Phase 1	Prototype Sites, Weapons Repair Facilities, Boiler Room, Central Transit Stations
Phase 2	Imperial Foundry, Munitions Warehouse, Mercenary Camp
Phase 3	Weapon Workshops (appear at random map locations)

The Imperial Foundry in Phase 2 is the single most valuable target — it carries the most Arsenal Points and will be contested by the strongest players on both sides.

How Scoring Works

You earn Alliance Arsenal Points and Personal Arsenal Points by taking and holding buildings, plus combat scoring:

Defense: ~40 points per 10,000 enemy Power defeated.
Offense: ~80 points per 10,000 enemy Power defeated.

The alliance with the most Alliance Arsenal Points at the end wins. Note that offense is worth double defense per power defeated — so an aggressive, objective-focused alliance has the edge.

Strategy: How to Win Foundry Battle

Prioritise the Imperial Foundry (Phase 2). Send your strongest players to capture and hold it — it's the biggest point swing of the match.
Play offense. Since offense scores double and troops don't die, keep attacking rather than turtling.
Hold what you take. Points accrue from maintaining control, not just capturing — leave defenders on secured buildings.
Coordinate registration and targets. A well-organised top-20 alliance beats a stronger but disorganised one.
