How many GB is Onyx?

0.2 GB

That is less than the typical Role-playing (RPG) game, which needs about 6 GB.

Leave at least 6 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 Rowan, a secluded witch with a bad temper, in this intense adventure worth 30-40 hours of gameplay!
