How many GB is The Missing Rune?

2 GB

That is less than the typical Simulator game, which needs about 4 GB.

Leave at least 8 GB free: games need headroom to unpack updates.

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

A psychological horror sim where you play a low-level researcher, who has to banish demonic entities back to where they came from. While having to keep the entitles in your peripheral vision, you must use the Rune Operation Manual to input the right runes, and send them back.
