Horizon: Forbidden West Ep.41: Water Troubles

We head back to the underwater ruins found by the Carja duo in No Man's Land, but despite defeating the machines causing their delving crew issues, Aloy can't hold her breath long enough to get a good look at the submerged ruins. So we head deep into the desert to the west, seeking out other ruins once known as Las Vegas in the hopes of securing the AI subfunction, Poseidon.
