How many GB is Mariana?

0.24 GB

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

Leave at least 6 GB free: games need headroom to unpack updates.

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

You are dropped into an unknown trench to explore. You will find fantastical creatures and rare artifacts. Fight bosses and mini-bosses in order to dive as deep as possible and uncover the mystery of the trench.
