About This Game

Mutually Assured Destruction

Doomsday: M.A.D. is a nuclear strategy game on a living planet. Nations are born on untouched land and write their own history: their towns grow, their economies and railways take shape, their rulers come and go, and their wars sometimes end in nuclear fire. Watch this world live, play god, or take control of one nation.

The Living World

Two to eight nations, each with its own name, tongue, regime and ruler. Towns grow district by district, ministers govern, farms, sawmills, mines, oil wells and uranium mines work real deposits, and railways and shipping lines carry food, wood, ore, oil and uranium.

Nations trade, ally, sign pacts and disarmament accords, go through coups, revolutions and secessions, and fight real wars with fronts, trenches, supply lines and landings, through the industrial, atomic and orbital eras. A Chronicle tells everything that happened.

Your turn

• Take control of a nation: build, lay your railway, settle colonies, set your taxes, negotiate peace and disarmament, lead your war.

• Play god: volcanoes, tsunamis, meteor showers, uprisings and weapons on demand.

• Save your world and come back to it centuries later.

• Make your own maps: relief, water, forests, biomes, resources, nations and towns.

Destruction you can read

• 16 weapons, from rocket salvos and MIRVs to the Tsar Bomba, an orbital beam, antimatter and a black hole

• Volumetric mushroom clouds and blast fronts that knock buildings over and stop against the mountains

• Craters that cut railways and roads, burning districts, flattened forests, sinking ships

• The bomb leaves dead land and a nuclear winter

Economy and logistics

Steelworks, refineries and arms factories turn what the land gives into what a war needs. A nation that holds its production chain pays half price for its weapons. Blow up a bridge or sink a tanker and the goods are lost.

For a shorter game

• War Mode: a crisis that builds from DEFCON 5 to DEFCON 1, each level clearing more weapons. Raise battalions, build tanks and artillery, send fighters, bombers and drones, launch your fleet. Or watch two AIs fight it out.

• The Duel: two nations, a headquarters, silos and defences each. Saturate their defences, then send the heavy warheads.

Maps and sound

Nine procedural map types, from a small island to a 131 km supercontinent. Real recorded sounds, air-raid sirens, blasts that arrive at the speed of sound, and music that follows the tension.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

Some of the game’s text (interface labels, descriptions and their translations) and the text of this store page were written with the help of an AI language model and reviewed by the developer. The rulers’ portraits and the start menu’s background are placeholder images made with an AI image model: they keep those spots from standing empty and are meant to be replaced by original artwork. Everything else on screen is rendered in real time by the game’s own engine, and its music and sounds are human-made recordings or synthesized by the game. No AI content is generated while you play.
