Headquarters: Your Most Important Building
Your Headquarters (HQ) is the heart of your entire base. Every other building’s maximum level depends on your HQ level. Higher HQ levels unlock better tech trees, stronger troops, and new game modes. If your HQ falls behind, everything else stops progressing. Make this your top priority at all times.
Tech Center: The Biggest Bottleneck
The Tech Center must match your HQ level for almost every upgrade. This building is the most expensive and time-consuming to upgrade, making it your biggest bottleneck. Without a properly leveled Tech Center, you cannot advance your HQ or unlock important research.
The Tech Center gives access to four major research trees:
- Development Tree: Reduces building costs and upgrade times
- Versus Duel Tree: Costs only Valor Badges instead of resources
- Special Forces Tree: Unlocks Tier 10 troops at level 20
- Combat Trees: Improve troop attack and defense stats
Focus on the Versus Duel Tech Center first because it uses Valor Badges instead of iron, food, and oil. This lets you progress without draining your main resources. Once you reach Tech Center level 20, unlock the Special Forces tree to access stronger troops.
Barracks: Training Your Army
The Barracks needs to match your HQ level for most upgrades. Higher Barracks levels unlock stronger troop types and increase how many troops you can train at once. Without upgraded Barracks, you cannot build the armies needed to fight zombies, defend your base, or attack enemies.
Training better troops requires both Barracks upgrades and Tech Center research. Make sure both buildings advance together. Falling behind on either one will limit your military strength and leave you vulnerable to attacks.
Builder’s Hut: Speed Up Everything
Of all the buildings to upgrade, the Builder’s Hut should be the first one. Each upgrade increases the free speedup time you get for finishing buildings instantly. At level 7, you get 2 minutes of instant completion. This might not sound like much, but it adds up quickly over hundreds of upgrades.
Hospital and Walls: Defensive Essentials
Several HQ upgrades require specific Hospital and Wall levels. These buildings protect your troops and base during battles.
| Building | Purpose | Why Upgrade |
| Hospital | Heals wounded troops | Prevents permanent troop losses |
| Emergency Center | Extra healing capacity | Saves troops that would die |
| Wall | Base defense | Reduces casualty rates when breached |
Upgrading your Hospital increases how many troops can be healed instead of dying permanently. The Emergency Center works as a backup hospital for overflow casualties. Higher Wall levels reduce damage speed when your base is on fire and lower your casualty rate during enemy attacks.
These buildings become critical after HQ level 25 when battles get more intense. Do not ignore them or you will lose armies worth millions of resources.
Combat Centers: Tank, Air, and Missile
Combat Centers (Tank Center, Air Center, Missile Center) boost specific hero types. Upgrading these buildings increases hero stats and march speed for their respective categories. Some HQ levels require specific Combat Center upgrades before you can advance.
Focus on upgrading the Combat Centers that match your strongest heroes. If you use Tank heroes most often, prioritize the Tank Center. Spreading upgrades across all three centers wastes resources if you only use one or two hero types regularly.
Embassy: Alliance Benefits
The Embassy lets you create or join alliances. Higher Embassy levels increase how much alliance help you can receive. At level 15, you get up to 12 help requests per upgrade or research. Each help reduces your waiting time, letting you finish projects faster without using speedups.
Upgrading your Embassy early gives long-term benefits. Every building and research you complete for the rest of the game will finish faster with maximum alliance help.
Buildings to Avoid Early
Some buildings look important but give poor value in the early game:
- Production buildings beyond basic levels
- Decorative or seasonal structures
- Storage facilities (only upgrade when required)
- Scout Center (only level as needed for HQ requirements)
These buildings use resources better spent on HQ requirements, Tech Center, and Barracks. Save them for later when you have excess resources.
Upgrade Order Strategy
Follow this priority order for maximum efficiency:
- Headquarters
- Tech Center
- Barracks
- Builder’s Hut
- Hospital and Walls
- Embassy
- Combat Centers
- Resource buildings
Focus on buildings that unlock HQ upgrades first. Check the requirements for your next HQ level and make sure those buildings are ready. Do not waste time on buildings that are not blocking your progress.
Smart building choices separate successful players from those who struggle. Upgrade the right structures, save your speedups for critical moments, and watch your power soar above the competition.
