Players eventually must confront a huge collection of Necromorph flesh known as "The Leviathan" in Chapter 6 of Dead Space Remake, using their accumulated weapons and supplies to beat the monstrosity before its toxic air spreads fully across the USG Ishimura. Located in the Food Storage, the Leviathan boss fight thankfully has a Save Station and Store that players can access prior to the boss room itself. Isaac must fight the huge amalgamation within an airlock using zero gravity, making this fight a bit tricky to manage as players must fully utilize unique movement options to avoid the Leviathan's attacks.
