How many GB is Inferno Protocol?

25 GB

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

Leave at least 35 GB free: games need headroom to unpack updates.

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

Trapped in a deadly labyrinth, you and 5 friends must scavenge, craft, and survive. Harvest monster parts for gear, inject experimental syringes to gain unique skills, and navigate trap-filled corridors. In this 6-player horror survival, you must evolve to escape.
