How many GB is Castan?

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.

Explore an open post-apocalyptic city, delving into buildings and businesses where mutated creatures run rampant, few survivors still operate in reclaimed buildings. Working to pay the mafia will be no easy task, as diving into the dangerous contaminated World to make a profit is a death sentence.
