How many GB is Protocol Aftertime?

15 GB

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

Leave at least 23 GB free: games need headroom to unpack updates.

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

Experience an action-filled third-person 3D platformer with mind-bending puzzles and foreign worlds in a story about hope and responsibility, reaching far in the past and beyond the future. Learn, to understand, become aware, to truly awaken.
