How many GB is Echo Pandemic?

8 GB

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

Leave at least 15 GB free: games need headroom to unpack updates.

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

You are a bat, and the aliens are afraid of you. Stalk occupied towns by echolocation, bite a single host, and let the virus do the rest. A stealth game where your weapon is a disease. Engineer strains, manage outbreaks, and stay invisible. The hunt starts at dusk.
