HQ / Base Upgrade Planner

Plan a Base level upgrade: see known prerequisites and resource costs.

Community-Sourced Data

Level requirements and resource costs (covering HQ2–HQ30) are transcribed from a player-created community rush chart, not official documentation. Treat the in-game requirement screen as authoritative if it differs — see the City & Base Rush Guide and HQ / Base Prerequisite Reference for the strategy and the full table.
