How many GB is Mister 9?

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.

Look for irregularities in the house where the uncles live. Irregulars are the enemy. For the sake of world peace, shoot without mercy.
