How many GB is Echo 9?

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.

Echo 9 is a tense first-person horror. You are Yon, a maintenance android. Navigate a failing shuttle through deep space, stabilize the dying reactor, and bring Eva to the evacuation point. Radiation is rising, the evacuation point far. Eva is in stasis. You are all she has.
