How many GB is Protocol Nightmare?

1 GB

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

Survive three nights of absolute terror while more than 10 monsters hunt you down. Explore secret paths, complete tasks, use your flashlight and scanner, upgrade your abilities, and face an intense survival experience.
