How many GB is Protocol Five?

6 GB

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

Leave at least 13 GB free: games need headroom to unpack updates.

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

Protocol Filve is a surreal first-person adventure with multiple endings, you will find yourself in a world where some rotten things want to kill you. Some choices along the way drastically and irreversibly change the game, leading to one of the 5 possible endings.
