How to use this reference
- Find your target HQ level.
- Check both required buildings.
- Compare Food, Metal, and Oil costs.
- Start preparing the following HQ level before the current Base upgrade finishes.
- Treat the in-game requirement screen as authoritative if it differs from this community reference.
High-level planning notes
- Alpha Research Division becomes a recurring prerequisite from HQ8 onward.
- Alliance Center appears at several key levels.
- Training Center (By class) appears repeatedly.
- Hospital, Defense Line, Drill Ground, and Soldier Training Camp rotate in as secondary prerequisites.
- Resource costs accelerate dramatically after HQ20.
- Keep flexible resource chests unopened until you know which resource is blocking the next upgrade.
Evidence:Transcribed from a player-created community HQ rush chart, not official documentation. HQ24's uneven Food/Metal requirement, the Alpha Research Division level jumps around HQ24–26, and HQ29/HQ30 sharing the same resource cost are unusual enough to be worth confirming against your account's actual next-requirement screen.
