How many GB is Outcast on Mars?

2 GB

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

Leave at least 8 GB free: games need headroom to unpack updates.

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

Two robots struggle to reverse a zombie apocalypse that has swept the human race from the earth's surface. However, a threat hides a terrible mystery in the most unlikely place in the solar system. The planet Mars!
