How many GB is Defense of the Earth?

1 GB

That is less than the typical Role-playing (RPG) game, which needs about 6 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.

Gather a task force of the best fighters earth has to offer and research technology to defend against the invaders out of space. You have to lead your squad through various grid- and turn-based battles. Between missions, you plan your next moves, manage your crew's abilities and relationships.
