How many GB is Defending Earth?

1 GB

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

As the Earth faces the greatest asteroid storm in the solar system, players must strategize and use a variety of weapons, tools and other resources to protect the planet. With a countdown to the incoming storm, players must act quickly and make strategic decisions to save Earth from the asteroids.
