How many GB is Nuclear War Simulator?

11 GB

That is more than the typical Simulator game, which needs about 4 GB.

Leave at least 19 GB free: games need headroom to unpack updates.

The figure is the storage Steam lists as required for this game, not a measured download.

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.
