How many GB is Welcome to Mars 9?

0.1 GB

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

Welcome to Mars 9: The Tale of River is an old-school graphic adventure about a person adrift in space, rescued by a luxurious space station orbiting Mars. Playing as River, you will be drawn into a world of comfort and pleasure, only to soon discover that the station hides a dark secret.
