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

Zoo Protocol is a co-op sci-fi horror game where you and your team are assigned to an abandoned alien industrial complex run by a malfunctioning corporate system. Care for dangerous anomalous creatures, prepare nutritional mixtures, process waste into energy, repair failing machinery, and meet ever-growing production quotas. Explore the facility, uncover the fate of the previous shift, and fight to escape before the system decides you're no longer needed.
