How many GB is Invisum Piscium?

2 GB

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

Leave at least 8 GB free: games need headroom to unpack updates.

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

An atmosphere-driven walking simulator where you explore familiar yet unsettling spaces, interact with fragmented conversations, and influence partial changes in the world through small actions, observation, and quiet choices that shape how the experience unfolds.
