How many GB is Nocturne for Cyl-Hestia?

5 GB

That is more than the typical Puzzle game, which needs about 3 GB.

Leave at least 11 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 memorialist and investigate a dystopian city in this 3D adventure game. Collect memories, unlock visions, hack encrypted data, and expose the truth in the face of a regime that manipulates memory.
