How many GB is Protect the Earth?

0.59 GB

That is less than the typical Adventure game, which needs about 5 GB.

Leave at least 6 GB free: games need headroom to unpack updates.

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

You are the best pilot in the space force and the earth needs you to protect itself from an alien attack. Protect the earth and then go to the invader's planet to finish them off once and for all.
