Each force has their own design of HQ, in line with their different schemes:
- Orange Star: The Empire State Building, New York, United States. In-battle images show a Capitol-like building
- Blue Moon: Saint Basil's Cathedral in Moscow, Russia.
- Green Earth: A Medieval castle. In-battle images, however, show a palace.
- Yellow Comet: Himeji Castle, Himeji, Japan.
- Black Hole: Black Hole's HQ alludes to the evil genius' lair/tower in science fiction.
Capture of a HQ
A slight difference can be noticed in enemy HQ capturing between AW and AW2, both in capture animation and on the map screen. In the former, the captured HQ maintains the original sprite with the color scheme of the conquering party (i.e. if Orange Star captures Blue Moon's HQ, the final animation, as well as the final map screen, will show the Onion-domed building colored red). In the latter game, instead, the building is substituted by a second instance of the attacking forces' headquarters (i.e. a red skyscraper is built when the onion-domed cathedral is lowered down).
