HeadQuarters

Your HeadQuarters is the command center of your army. It is a one-time building project that advances a little each turn until it is complete.

Build it early. The price goes up every turn you play, up to a ceiling. It does not depend on how large your realm is.

While it is being built — and more so once it is finished — it raises how much your tanks add to both attack and defense. When you lose a battle as the defender, some of its progress is lost. When an invasion from another planet beats you, a fifth of it is lost. Agents from another planet can also sabotage it.
