How many GB is Upstream?

0.15 GB

That is less than the typical Platform game, which needs about 2 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.

Play as a salmon journeying home in this challenging physics based platformer using only two buttons! Remember that on a voyage through innumerable obstacles and constant danger, it is your reaction to adversity that determines your success.
