You can declare war on other nations in the game and capture their buildings using your military units. In order to declare war on another nation:
- Both nations must have War mode enabled
- The nation must be in the same economic Age as you
- The nation must not be in the same Alliance as you
- You and the other nation must not already be in a war
War mode turns on automatically when you reach the Industrial Age. You can opt out in Nation Settings, but re-enabling has a 12-hour cooldown so you cannot duck fights and then immediately declare war.
🕗 12 hour cooldown for declaring and being declared on
🛡 Losing a war grants a free 24-hour war shield
While at war, economic turns are paused — the dashboard Next → button becomes ⚔️ Manage War. Progress happens through battle turns instead.
Deploy military units to defend your 🏢 Buildings.
Deploy military units to attack and capture your opponent's 🏢 Buildings. Targets a defender leaves completely unguarded may be razed instead of captured, so keep an army fielded. And war pays nothing when it costs nothing — spoils from a war won without meaningful resistance are returned to the loser when the war ends.
Launch 🚀 Missiles at an enemy building. Damage is compared to building HP — destroyed buildings are removed from the map (not captured). Missile strikes cause civilian casualties.
Launch ☢️ Nukes or Atomic Bombs at an enemy target. Nuclear weapons deal heavy damage, destroy buildings, and cause mass civilian casualties. They also raise the defender's national radiation level, which increases sickness until it decays over time.
National radiation caps at 100 and decays slowly each economic turn. There is no global fallout in Classic.
Deploy 🦠 Bio Bombs or ☣️ Pandemic weapons against an enemy target. Biological weapons leave buildings standing but kill units garrisoned there, inflict large civilian casualties, and spread ☣️ national sickness that raises illness until the outbreak subsides over time.
National sickness caps at 100. Outbreaks hit harder than radiation but clear faster with each economic turn.
Deploy a disposable 🛰️ Satellite over an enemy building. The satellite is consumed on use and snapshots enemy unit counts at that target. Revealed enemy units appear in blue on future battle planning screens.
Propose tribute (influence or resources) from the war dashboard. Your opponent can accept, counter, or reject. On acceptance, tribute is exchanged and the war ends. Unconditional surrender remains available at any time.
End the war immediately with no tribute.
Battle Reports are generated after each battle once a turn is completed. Skirmishes show military units lost (KIA) and buildings captured on offense. 🚀 Missile and ☢️ nuclear strikes show buildings destroyed and civilian casualties on the defender. ☣️ Biological strikes show unit and civilian losses plus the national sickness inflicted.
