Which Buildings Should You Upgrade?

One of the easiest ways to slow your HQ progression is spending resources on buildings that don't help unlock your next HQ.

HQ8–30 Requirement Pattern

From HQ8 through HQ30, the supplied guide identifies the Laboratory as mandatory for every HQ upgrade.

The second required building rotates among:

• City Walls
• Alliance Center
• Assaulter Camp
• Shooter Camp
• Rider Camp

Think of your progression as:

Laboratory + Required Rotating Building → HQ Upgrade

For HQ31–35, requirements should instead be planned level by level using the later-game requirements.

Buildings to Avoid Upgrading Too Early

Unless they're required for your next HQ or serve an immediate strategic purpose, avoid pouring resources into:

• Resource production buildings
• Hall of Honor buildings early in progression
• Random buildings simply because they show a blue upgrade arrow

A blue arrow means you can upgrade something—not necessarily that you should.

Useful Optional Upgrades

When resources and construction time allow, the supplied guide identifies these as useful:

• Formation buildings
• Military Center
• Bookstore
• Restaurant
• Production Center
• Rally buildings
• Radar

The HQ Progression Rule

For players trying to reach higher HQ levels efficiently:

Upgrade what your next HQ requires first.

Then use spare construction time and resources for secondary buildings that provide meaningful benefits.

Final HQ35 Planning

By the time you're approaching HQ35, your progression should be deliberate rather than reactive.

Remember the big numbers:

HQ30 → Hero Cap 150

HQ35 → Hero Cap 175

HQ31–35 → 21.1M Total Steel

Plan the required buildings, Steel, speed-ups, construction bonuses, and event timing before pressing Upgrade.
