How many GB is Altarium?

20 GB

That is more than the typical Adventure game, which needs about 5 GB.

Leave at least 29 GB free: games need headroom to unpack updates.

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

Altarium is a first-person, asymmetric PVP Co-Op horror game that can be played by 1-5 players together. Players can choose to play as either the victim or the evil character. Get ready, choose your role, shape your destiny, and survive!
