How many GB is Signal Zero?

3 GB

That is less than the typical Shooter game, which needs about 8 GB.

Leave at least 9 GB free: games need headroom to unpack updates.

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

A sci-fi roguelike shooter where aim and movement are unified into one mouse. Pilot a Simuler, command your ship, deploy escorts, and tear through colossal bosses. Easy to grasp, ruthless under pressure.
