Nuclear War Simulator Direct Download

Nuclear War Simulator is a detailed realistic simulation and visualization of large-scale nuclear conflicts with a focus on humanitarian consequences. There are currently over 13000 nuclear weapons on this planet of which over 9000 are in military stockpiles. This software should help you answer the question: what will happen if Russia and the United States or India and Pakistan use their arsenals?
You can design warheads, missiles and carries, place them on the map and execute attack plans to tell a credible story about how nuclear conflicts play out and what are the consequences. Using a high-resolution population density map and realistic weapons effects like blast, heat and radiation you can make an estimate of how many people will die in a conflict.

Nuclear conflict scenarios

You can design realistic large-scale scenarios between major powers with thousands of warheads. Scenarios can be created manually where you can assign each warhead individually or with the assistance of an AI for faster targeting. It is also possible to simulate whole conflicts with a few clicks on the map interactively. You can download scenarios created by other people and upload your scenarios to the mods.io server.

Realistic effects of nuclear weapons

The simulation includes a high-resolution population density grid. The effects of blast, heat, fires and radiation are calculated and visualized for each population cell to estimate fatalities (similar to Alex Wellerstein’s NUKEMAP). The destruction of military targets is simulated using a model considering the CEP of the weapon, target hardness and cratering.
You can place yourself, your family and friends into the simulation to estimate the expected injuries and survival probability. The amount of burnt fuel and produced soot are also calculated to estimate the effects of nuclear winter using a simplified model.
