Is Nuclear War Simulator worth it for you?

We tell you who should skip it, too.

Play it if you…

Good fit
  • Simulation players who want to model nuclear conflicts and their humanitarian consequences
  • Players who want to design warheads, delivery systems, and large-scale attack plans
  • Players interested in map-based scenarios involving population effects, missile defence, and civilian sheltering

Skip it if you…

Saves you a refund
  • Players seeking character progression, conventional combat, or a story-driven campaign
  • Players looking for short, action-focused sessions rather than detailed scenario construction and consequence modeling
  • Players who do not want simulations centered on nuclear attacks, casualties, radiation, and fires

Our take on Nuclear War Simulator

Its defining detail is the population-grid modeling of nuclear attacks, which maps blast, heat, fires, and radiation across civilian cells to estimate casualties and other humanitarian effects.

What is Nuclear War Simulator?

Nuclear War Simulator models large-scale nuclear conflicts and visualizes their humanitarian consequences.

Users design warheads and delivery systems, position forces on a map, and create attack plans manually, with adjustable AI assistance, or through interactive map controls. The simulation calculates blast, heat, fires, radiation, military-target destruction, civilian casualties, and sheltering behavior across a high-resolution population grid. It also estimates burned fuel and soot using a simplified nuclear-winter model. The software includes 22+ editable scenarios, early-warning and missile-defence systems, and locations imported from KMZ files. Detonation lists can be imported from CSV files or exported with soot data. Users can share scenarios and blueprints, download scenarios from others, and modify selected textures, loading screens, and background music.

How Nuclear War Simulator plays

01Conflict Scenarios
Users can assign warheads individually, use adjustable AI targeting, or simulate attacks through map-based controls.
02Population Effects
A high-resolution population grid displays blast, heat, fire, and radiation effects for each population cell.
03Target Destruction
Military damage calculations consider weapon CEP, target hardness, and cratering.
04Civilian Behavior
Individual civilians move across the map and can seek shelter during simulations.
05Editable Scenarios
The software includes 22+ predefined scenarios that can be modified.
06Location Data
Real-world positions can be imported from KMZ files.
07Detonation Data
Detonation lists can be imported from CSV files or exported with associated soot data.
08Scenario Sharing
Scenarios and unit blueprints can be shared, while scenarios made by others can be downloaded.
