How many GB is Mutation?

6 GB

That is less than the typical Shooter game, which needs about 8 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.

Mutation is a procedural Dungeon Crawler Roguelite with survival and RPG elements, set in a sci-fi Lovecraftian theme: gain experience, unlock skills and new items, face increasingly dangerous threats, and escape through different paths while exploring multiple levels and uncovering the organization's secrets.
