How to fight
Defend: with DEFEND selected, tap the sky ahead of an incoming missile. Your defence missile bursts there and destroys anything in the blast.
Attack: pick a weapon and tap countries to fire. Hold your finger on one for rapid fire. The card shows the target's strength. Fighters fly a fast, light air strike on an enemy — or, tapped over a territory of yours, patrol it and shoot down low incoming strikes. Satellites go over a territory of yours and guard it.
Capture: the number on each country is its strength in millions. It's a sustained attack: every country slowly heals itself, and the healing scales with how much of it still stands — so a country near collapse can barely recover. Out-damage its healing to grind it down; knock it to 0 and it's yours, with any base on it. Every territory you hold makes your bases build faster.
Neutral countries leave you alone until you hit them, then they fire back — until you take out the bases and government they fire from.
War mode: tap a country, then ⚔ WAR. A close-up opens beside the globe with its government, air defences, bases, factories, power grid, railway, roads and bridges. Tap a site to strike it. Air defences shoot your strikes down and bases fire back until you destroy them. While you're at war a country can't rebuild anything — destroy every one of its sites and it falls to you. Leave war mode and it starts repairing again, so finish what you start.
Open ground: in war mode tap anywhere, not just a site: the spot blows up and catches fire. Fire spreads, fastest through forest and farmland, and burns any site it reaches.
Troops: ground forces only cross a land border. Pick TROOPS and tap a country you own a land-bordering neighbour to; the close-up opens, and each tap on the ground sends a battlegroup across the border from your nearest bordering territory — artillery shells from the frontier, tanks punch into the military sites, infantry take ground behind them. Islands and countries you don't border by land can only be hit by missiles, bombers, subs and satellites. HQ and naval bases train troops.
Rebuilding: any country not currently at war rebuilds its wrecked sites and heals over time — the ones you take, and enemy or neutral ones you walked away from. Right-click or ⚔ one of yours to watch.
