How many GB is Upstream?

2 GB

That is less than the typical Indie 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.

A physics-based upstream paddling challenge where every move matters. Navigate treacherous waters, dodge deadly obstacles, and fight against the current—but one wrong touch shatters your fragile glass boat, sending you back downstream. A brutally hilarious test of patience and skill.
