How many GB is Mutagen Extinction?

8 GB

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

Leave at least 15 GB free: games need headroom to unpack updates.

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

Live unlimited adventures with your friends in an incredibly beautiful and extensive world, build your future and unravel the ancient arcane arts of the elderly, defend your home from mutated creatures and other survivors.
