Bases in World War Online

What is the HQ base?

World War Online features several types of bases, each with its own purpose and strategic importance:

  • Headquarters Base - Your primary base that provides Iron production and unit training
  • Capital Bases - Strategic conquest points in Capital Warfare that determine winners
  • Military Bases - Specialized bases for training Special Forces units
  • Resource Bases - Generate various resources (Money, Food, Brick, Iron)
  • Mine Bases - Specialized in high-volume Iron production

Headquarters Base

Upon creating an account in World War Online, you will receive a Headquarters Base placed randomly in the territory of your Country, which cannot be relocated.

The Headquarters Base is your primary base that provides steady Iron production and serves as your main training facility where you can train Supreme Units and Generals. Upgrading your Headquarters increases your Iron production and provides additional strategic advantages. Although your Headquarters can be raided for resources, it cannot be conquered or destroyed.

Headquarters Defense Bonus

Districts containing your Headquarters provide enhanced defensive capabilities:

  • 8 unit groups can be positioned for defense (instead of the standard 6)
  • 4,000 normal units can be deployed (instead of the standard 3,000)
  • This strategic advantage helps protect your command center and surrounding territory
  • The headquarters defense bonus is indicated with a special badge in the district view

Mine Bases

Mine Bases produce significantly more Iron than Resource bases but are limited to 4 per player. They have the highest Iron production rate among all base types, making them valuable for players who rely heavily on Armored and Sea units.

Base Construction Costs

Building Mine Bases requires WWO-Influence, with costs increasing for each additional mine:

Military Bases

Military Bases are specialized bases that allow you to train Special Forces units. You can build up to 5 Military bases per player. These bases serve as forward operating positions and training facilities for your elite tactical units.

Base Construction Costs

Building Military Bases requires WWO-Influence at a fixed cost: - Construction Cost: 2 WWO-Influence per base

Capital Bases

Capital Bases are special bases that are automatically generated inside world capitals during Capital Warfare events. These bases are fundamental to winning the game, as conquering and holding them earns points for both the Squad Leaderboard and Player Leaderboard.

Key Features: - Automatically created when a Capital Warfare event starts - Cannot be constructed by players - only conquered - Cannot be upgraded or modified - Cannot be destroyed - only conquered and defended - Earn competitive points for your squad and personal ranking when held - Strategic importance: Controlling capital bases is how squads win seasons and earn rewards

Capital Bases represent the ultimate strategic objectives in World War Online. Coordinating with your squad to conquer and defend these bases during Capital Warfare events is essential for achieving victory and climbing the leaderboards.

Automatic Base Defense

Your bases feature automatic defense setup to ensure they're never left completely undefended:

  • Auto-Defense System: When you haven't created a defense setup yet or have insufficient units positioned, the system automatically sets up defenses using your strongest available units
  • Smart Prioritization: The system prioritizes your largest unit groups first and maximizes unit type diversity to create a balanced defense
  • Strategic Positioning: Units are placed strategically to maximize defensive effectiveness
  • Fully Customizable: You can still edit and customize these automatic defenses at any time to match your preferred strategy
  • Complete Control: You maintain full control over your defensive strategy while having a solid baseline defense automatically created
  • Peace of Mind: Never worry about leaving a base undefended - the system has you covered

This feature is particularly useful when managing multiple bases, when you need to quickly set up defenses across your territory, or when enemy units in districts become visible and targetable.

Defense During Incoming Attacks

When enemy attacks target your base district, your defense enters a "pinned" state that restricts certain strategy changes. Understanding which strategies you can modify during active attacks gives you crucial tactical flexibility to counter incoming threats. For information on how Tactical Units interact with these dynamic strategies, see the Tactical Units guide.

What You Can Change (Dynamic Strategies)

Even when your defense is pinned, you retain control over dynamic positioning strategies. These flexible options allow you to respond tactically to incoming attacks:

Strategy Wave Entry Description Tactical Advantage
Ambush Wave 4 Units wait in concealed positions before engaging Position units to counter attack formations after you see enemy composition; ideal for targeting Generals on Wave 11
Flank Wave 8 Units maneuver to attack from advantageous positions Adjust positioning mid-battle to exploit enemy weaknesses; can be set for any battle position

Dynamic strategies give you the power to adapt your defense even after attacks launch. You can set up ambush positions to target incoming Generals, adjust flanking maneuvers to counter specific unit types, and fine-tune your tactical response based on enemy attack patterns.

What You Cannot Change (Static Strategies)

When your defense is pinned, these fundamental strategies become locked and cannot be modified:

Strategy Description When to Configure
Default Standard unit positioning with normal engagement Set before attacks arrive; provides balanced all-purpose defense
Hold Units maintain their positions defensively Configure ahead of time for position-holding tactics
Conquer General-focused strategy for preventing conquest Establish before enemy conquest attempts begin
Destroy Special Forces-focused strategy for preventing base destruction Set up proactively when destruction threats are expected

Static strategies form your defensive foundation. Since you cannot modify them during incoming attacks, plan your base defenses carefully before threats materialize.

Strategic Tips

Maximize your defensive advantage with these tactical approaches:

  • Set static defenses proactively: Configure Default, Hold, Conquer, and Destroy strategies before attacks arrive. Once enemies launch attacks, you lose the ability to adjust these foundational defenses.

  • Use dynamic strategies as counter-measures: Add Ambush or Flank strategies even after attacks have launched. If you see a General in an incoming attack, position Ambush units near the Wave 11 spawn points to eliminate the conquest threat.

  • Position Ambush for General elimination: When defending against conquest attempts, Ambush units entering on Wave 4 give you seven waves to thin enemy forces before the General arrives on Wave 11. Focus anti-infantry units in ambush positions near likely General spawn locations.

  • Adapt Flank positions to enemy composition: Since Flank units enter on Wave 8, you can adjust their positioning based on the enemy attack formation you observe. Counter infantry-heavy attacks with anti-infantry flankers, or respond to armored threats with appropriate unit types.

  • Layer your defenses: Combine static foundational strategies with dynamic tactical responses. Use Default or Hold strategies for your primary defense line, then supplement with Ambush or Flank units to create multi-layered defensive depth.
