Plan your next HQ upgrade
Choose a target HQ, enter your completed building levels, and see the direct gates you still need. HQ31–35 also shows direct HQ resource estimates.
Next-HQ readiness check
Use this guide for a direct readiness check. It does not calculate the resource cost of prerequisite building upgrades.
Enable JavaScript for the interactive checklist. The requirements table below remains available without it.
A target is ready only when every direct requirement has been verified. Unknown values are not counted as complete.
How to use this check
- Select the HQ level you want to build next.
- Enter only the building levels you have actually completed; select your troop Center.
- For HQ31+, confirm HQ Expansion research and optionally enter available resources.
- Review missing levels, then open your live HQ screen to confirm final costs.
Oil and Age of Oil research are part of the HQ31+ progression route.
Direct HQ requirements
One troop Center is enough: Tank, Aircraft or Missile. HQ31 also requires HQ Expansion research.
