How many GB is Iron Core: Mech Survivor?

4 GB

Leave at least 10 GB free: games need headroom to unpack updates.

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

100 years after a nuclear apocalypse, an AI-managed shelter and its guardian mechs await human survivors. The shelter’s reactor creates safe zones to improve living conditions. Players control mechs to gather reactor fuel, fend off mutants, complete missions, and protect survivors.
