The shipboard oxygen levels became critical as a result, and with the creation of poison-exuding Necromorphs known as the Wheezers, the Hydroponics Deck became unable to support human life.

Shortly after, the tracts of the Corruption began to spread at an exponential rate in close proximity to the Leviathan and proceeded to overtake much of the deck. Another possibility is that that it was extracted from the planet along with the tectonic load that the Ishimura lifted with its gravity tethers, as this would make it feasible for it to have floated onto the ship on its own.Īfter colliding with the ship, the Leviathan made its way into the Hydroponics Deck and barricaded itself inside the Food Storage facility. This would account for the additional mass it has, along with the contents of Food Storage.

The Leviathan collided with the USG Ishimura while drifting through space. The origin of the creature and how it ended up in space is a mystery, though it is possible that it was ejected from the surface of Aegis VII by the Hive Mind and was initially made up purely of the colonists' biomass.
