How many GB is The Origin Theory: Episode One?

30 GB

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

Leave at least 41 GB free: games need headroom to unpack updates.

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

Origin Theory episode one is a lighthearted story driven survival horror experience. Game has it's classic bad guy, zombies, guns and nasty stuff, but the emphasis is on unraveling the mystery and not grinding down hordes of enemies and surviving bullet soaking boss fights.
