How many GB is Operation Athena?

20 GB

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

Leave at least 29 GB free: games need headroom to unpack updates.

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

Operation Athena is a tactical first person shooter that takes inspiration from classic tactical shooters with updated modern mechanics. Take part as an operator of Athena Team solo or with up to 4 players against a global terrorist threat.
