How many GB is Alternis?

10 GB

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

Leave at least 17 GB free: games need headroom to unpack updates.

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

"Alternis is a hack and slash combat game in first and third person, for single player and multiplayer, still in the early stages of development."
