How many GB is Chernobyl: Simulator?

30 GB

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

Leave at least 41 GB free: games need headroom to unpack updates.

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

Chernobyl Simulator puts you in the control room of the most infamous nuclear power plant in history. Step into the shoes of a reactor operator, where every switch, gauge, and decision matters. Experience the pressure, responsibility, and unforgiving complexity of Soviet-era nuclear operations.
