How many GB is Earth vs. Mars?

8 GB

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

Leave at least 15 GB free: games need headroom to unpack updates.

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

Faced with a terrifying Martian invasion, you must lead Earth’s forces in a battle for our planet’s future. Create powerful human-creature super soldiers to fight an alien menace in this turn-based strategy game.
