- Nuclear War Simulator - Fallout (4/6) - 30 April 2024
Hello Nuclear War Simulator fans. Episode 4/6 of our video series is out now. This episode explores the damage nuclear weapons do indirectly. While the explosion, blast, and fireball have the capacity to destroy cities, fallout can destroy whole ecosystems. When an atomic weapon explodes, the ash and dust sucked up into the atmosphere rains back down on vast swathes of countryside, contaminating everything it touches with radioactive material. This episode is all about how this phenomenon functions, studies about fallout, and what you can do to avoid it.
- Nuclear War Simulator Featured in Scientific American - 16 January 2024
Nuclear War Simulator's fallout model has been used in a scientific study commissioned by Princeton University. The Missiles on Our Land Project has utilized the NWS fallout model to track the different ways seasonal winds could effect the spread of radioactive ash and dust. This project specifically focused on modeling strikes on silo's in Montana, North Dakota, Nebraska, Colorado, and Wyoming. Here's a look at the interactive map using the NWS model. An example of the fallout map made using data from Nuclear War Simulator We are incredibly proud to see Nuclear War Simulator featured in studies like this. The ability to model a nuclear war and fallout accurately was previously only available using proprietary software. With this game commercially available, it is now possible for anyone to authentically model the devastating impact of nuclear weapons from the blast and firestorm, to th…

- This 'professional' end-of-the-world simulator is now available on Steam - 2 February 2023
t first glance, Nuclear War Simulator , which launched today on Steam, bears a real resemblance to DEFCON, the old (and excellent ) Wargames-inspired strategy sim about turning the planet into a roasted chestnut. In reality, it's something quite different, and not really a game at all: It's "a detailed realistic simulation and visualization of large-scale nuclear conflicts with a focus on humanitarian consequences."..

- Nuclear War Simulator Out Now - 2 February 2023
Nuclear War Simulator Out Now Nuclear war simulator is a detailed realistic simulation and visualization of large-scale nuclear conflicts with a focus on humanitarian consequences. It lets you design conflict scenarios and estimate the consequences using a population density map and realistic weapons effects. 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. Using an intuitive UI you can design warheads, place them on missiles and into silo…
