Economic roles
AllThingsHow and TheGamesEdge independently describe cities and factories as economic priorities. AllThingsHow alone reports a +25,000 troop-capacity increment per city. That exact increment is single-source, checked 27 October 2026.
Historical HUD prices
Historical RobloMine HUD, single source: city 500K, port 500K, factory 500K, defense 150K, silo 1.5M, SAM 1M, warship 750K, and nuclear buttons 750K / 5M / 25M. These are one frame’s labels, not a current universal price list. Reviewed 27 October 2026.
Different published prices
AllThingsHow’s separate price table lists a silo at 1M and SAM at 1.5M–3M; its city and factory tiers range from 125K to 1M. The silo and SAM figures differ from the historical HUD. Upgrade, mode and recording-date context is not fully established, so we preserve both records without selecting or averaging a current price. Checked 27 October 2026.
Defensive and naval roles
AllThingsHow describes the missile silo as the prerequisite for nuclear weapons, SAM launchers as interceptors and warships as naval units. The 70-tile SAM range is one publisher’s claim. No independently corroborated range or current price is supplied here.
Port price reports differ too
AllThingsHow’s overview reports a 125,000-gold starting port tier, while its 80-percent explainer reports 250,000–1,000,000 gold for ports. Both belong to the same publisher, not two independent confirmations. The disagreement remains unresolved; this page does not substitute either figure as a verified current price.
