How many GB is Operation Octo?

2 GB

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

Leave at least 8 GB free: games need headroom to unpack updates.

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

Dr. Odin, a hyper-intelligent octopus, is on a conquest against sunken skeletons. High-tech turrets are at his aid: Pistol Shrimp! Navy Seal! Death Ray! Deploy 'em, guard 'em, and collect more of 'em! Travel across unique biomes and put the dead to rest.
