How many GB is Unit Zero: Operation Black Veil?

30 GB

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

Leave at least 41 GB free: games need headroom to unpack updates.

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

Unit Zero is a first-person multiplayer shooter with realistic bodycam-style graphics made in Unreal Engine 5. Includes competitive and cooperative zombie modes. Investigate what went wrong in the secret operation that unleashed the nightmare.
