How many GB is IllumaNet?

1 GB

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

Leave at least 7 GB free: games need headroom to unpack updates.

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

Build a living network across the dark. In this strategic incremental game, connect distant stations with pulse bridges, turn every cycle into Data, and manage limited Grid Power as you scan the unknown and expand into strange new biomes.
