Adaptation Deviation: It deviates more and more as it goes on, but never too far for it to be a completely new story.Internal sections of the ship that are in a vacuum are changed from life supports failing to pockets of poison gas from The Leviathan.Isaac doesn’t even learn about The Leviathan until encountering an Almost Dead Guy in Mercer’s office who tells him about it before dying. Mercer in order to kill Isaac for getting in the way of his plans. Chapter 5 as a whole was changed from a mission to mix a poison to kill The Leviathan where Isaac coincidentally meets, and is subsequently antagonized by Dr Mercer and The Hunter, to Isaac responding to a message seemingly sent by Nicole, which turns out to be a trap set up by Dr.


Unfortunately, it doesn't save him from Mercer's treachery, but at least he puts up a fight. He's even packed with a Force Gun to brave the undead halls of the Ishimura. Rather than desperately searching for an SOS beacon in the original game, he's responsible for creating it, as well as many of the traps Isaac finds in the Mining Deck.
