How many GB is Idun?

1 GB

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

Explosive singleplayer action RTS with a story campaign. Hold the line against massive swarms on a fully simulated battlefield.
