How many GB is Meltdown?

0.49 GB

That is less than the typical Puzzle game, which needs about 3 GB.

Leave at least 6 GB free: games need headroom to unpack updates.

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

Meltdown is a nuclear reactor management simulation where you, a new recruit, must urgently operate the reactor to prevent a city-wide blackout. Your primary objective is to maintain the alignment of power grids, regulate the water flow and ventilation to keep the reactor cool, and deal with your manager’s nonsense.
