Geoplanetical war guide

This is an editorial checklist built from the official war documentation, not a playthrough report. The linked invasion showcase is optional context; no unrecorded viewing experience, timestamp, or unit count is offered as evidence.

What changed in war since launch

• 1.0.2 (29 Oct): you can give up nuclear weapons; nuclear powers can order new warheads and delivery systems.
• 30 Oct: puppet states and protectorates fight alongside their overlord in all its wars; defeated countries no longer refuse peace while an ally fights on.
• 31 Oct: the ammunition stockpile target rose from 200 to 540 days; amphibious landings no longer freeze and beachheads keep sea supply.
• 1.0.6 (1 Nov): domestic arms industry, foreign purchases, arms sales, and new Arsenal tabs. See the 1.0.6 and 1.0.7 write-up.
• 1.0.7 (1 Nov): peace summits, sanctions deals tied to a ceasefire or withdrawal, and NATO applications.
• 2 Nov: move troops to your own or allied bases and form groups before war.

Before you declare

Pick a reason, from defending an ally through conquest. Set territorial goals. Read the international reaction, the ministers, and the stability and approval cost. Allies do not join an offensive war on their own. You can ask them. The store page is the source for that sequence.

Three checks before advancing

1. Equipment: Defence, Arsenal. Since 1.0.6 the Arsenal has Stocks, Procurement, Industry and Contracts tabs. You choose between domestic production, foreign suppliers and surplus, comparing price, model, delivery time and maintenance. The contract needs the full cash up front. Gear arrives in batches.
2. Ammunition: Reserves and flows show in storage, with units, and 30 days of use against deliveries. The depot target is days of combat coverage; the default target has been 540 days since 31 Oct 2026. Lowering the target does not cancel orders already placed. A cut-off unit is not resupplied.
3. Staff orders: hold, limited pressure, or a major offensive, plus a theater priority and a targeting doctrine. Amphibious landings can be ordered or left to the staff.

If the advance stalls

Editorial decision path: review reserve coverage and incoming deliveries before increasing offensive commitments. If deliveries cannot sustain the current plan, reconsider the staff order rather than assume more equipment alone solves the problem. Check whether supply can reach the unit, then review the cash required for new orders. No fixed army size or ammunition threshold is recommended without evidence.

Peace is narrower than the map you painted

You can annex only occupied provinces that were inside the war goal. Since 1.0.7, peace summits can negotiate a ceasefire or armistice between any countries at war. A ceasefire pauses combat and does not move the border. An armistice pauses it indefinitely. After occupation you administer, repress, or expel. Hostility can become an uprising. Civilian deaths and displacement change foreign reactions and sanctions.

Nuclear weapons, as written

The wiki describes a deterrence doctrine, an alert ladder that climbs one step every seven days above Vigilance, and an umbrella. The nuclear room offers Major cities or Capital first, then PREPARE, then FIRE. Soot cuts sunlight and hits crops, fisheries, and solar. I have no third-party test of those consequences. The description stays first-party.
