How many GB is Tellus: Echo of the Void?

30 GB

That is more than the typical Adventure game, which needs about 5 GB.

Leave at least 41 GB free: games need headroom to unpack updates.

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

Adapt a barren world to sustain human life. Explore, gather materials, and establish your base. Then, manipulate the environment by producing air, warmth, and atmospheric pressure to create a living ecosystem.
