How many GB is Imperius?

10 GB

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

Leave at least 17 GB free: games need headroom to unpack updates.

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

Imperius is an easy-to-learn, hard-to-master space RTS with a lore-rich campaign. Command devastating ships of the Imperius Navy and prove your loyalty by destroying everything in your path, no matter the cost.
