Chapter 1 Changes

Chapter 1: New Arrivals Walkthrough

Johnston is Left in the Kellion

In the original game, every one leaves the Ishimura to check the Flight Deck of the Ishimura. In the Remake, Security Officer Hailey Johnston is left to watch over the ship. This also means that when Isaac returns to the Kellion at the end of Chapter 1, Johnston gets blown up along with the Kellion.

Isaac Builds the Plasma Cutter

Isaac now shows off his engineering skills by building the Plasma Cutter instead of merely picking it up from the workshop table.

Maintenance Bay Circuit Breaker

The remake introduces a new system of getting around the Ishimura using Circuit Breakers. This now allows you to reroute power to different sections of the Ishimura allowing to you unlock doors at the expense of lights or life support.

Maintenance Bay Office

In the original, you only had to get a key from the upper levels of the Maintenance Bay to get the Data Board. Now you have to sacrifice the lights to get the Data Board.

Chapter 2 Changes

Chapter 2: Intensive Care Walkthrough

All New Transit to Medical

In the original game, players would just have get on the Tram Station at the end of Chapter 1 to reach the Medical Deck. However in the remake, players would have to take a back door entrance from the Flight Deck Tram to get to the Medical Cargo Depot and then take an elevator to reach the Medical Deck.

Kinesis Module and Pulse Rifle Pickups

Originally, the Kinesis Module was given to you by the dying woman just as you arrive in Medical. In the remake, the Kinesis Module is picked up along the way when you traverse from the Flight Deck to Medical. The Pulse Rifle, on the other hand, was originally bought when you reach the Store at the end of Chapter 1, but is now instead, given to you by aforementioned dying lady!

Necro-Chen Attacks Hammond and Daniels

In the original game, a Leaper can be seen attacking Hammond and Kendra when they get separated. However in the remake, Hammond swears that the thing that attacked them was Chen, the security personnel killed by the Slasher in Chapter 1.

Barricade Explosive Components

The components needed to make the explosive for the barricade has been changed. A Hydrazine Tank is now needed instead of Thermite, but the Shock Pad still retains its name.

Shock Pad Acquisition

The Shock Pad will no longer just be sitting idly inside a room for you to pick up. They will now be live and pulsing with electricity. Shut them down with the Circuit Breaker in the Limb Stimulation Therapy Room to safely get them.

Hydrazine Tank Acquisition

The inner doors in Zero-G Therapy no longer require any power cell to open. You can simply hover from one end to another and open the door with ease to get the Hydrazine Tank. The way back is also different now, instead of simply retracing your steps, the remake redirects you to explore a completely different section to get back to the Security Station.

Isaac Gets to Flex His Skills Once More

Isaac again flexes his skills as an engineering and creates a Dead Space equivalent of C4 to blow up the barricade. While he also does this in the original, this time around we get to actually see him create the bomb instead of just strapping it to the barricade.

Hall to the Morgue Gets Blown Up

For dramatic effect, the game now blows up the hallway leading up to the Morgue. This creates a sense of urgency as initial playthroughs of the game may leave you with less oxygen than what you would want in a vacuum environment.

Captain Mathius Transforms Before Your Eyes

In the original game, when Captain Mathius is transformed into a Necromorph it all happens in the safety behind glass. This time the transformation gets upclose and personal as the Captain transforms right before our eyes.

Chapter 3 Changes

Chapter 3: Course Correction Walkthrough

Hovering to Engineering

The journey to the Engineering Deck now feels larger as you have to physically travel to Engineering unlike in the original game where the Tram is the only method of reaching certain sections of the Ishimura.

Refueling the South Station Requires More Steps

The refueling of the South Engine requires a bit more steps now. You have to find a Fuel Station Keycard to open Fuel Management and reroute power to the Engine. You also would have to choose whether or not you will lose sacrifice the lights or the life support as you refuel the North Engine.

Centrifuge Now Turns Counter-Clockwise

When you activate the Centrifuge in the original game, it spins clockwise, prompting you to run towards the right. In the remake, the Centrifuge now spins counter-clockwise prompting you to run to the left instead.

How to Activate and Get Past the Centrifuge

Path to Engine Room is now Zero-G

Instead of the linear path, to the Engine Room, the path is now a zero-g zone where you have to interact with the circuit breaker behind the fans to open the airlock, then burst the sac obstructing the door to the Engine Room.

Restarting the Engines Require a Power Cell

Likewise the layout of the Engine Room has also changed. Instead of just entering and interacting with the central terminal. You have to put in a power cell and only then interact with the terminal to reignite the engines.

Chapter 4 Changes

Chapter 4: Obliteration Imminent Walkthrough

Hull Breached in the Bridge

Again for dramatic effect, the Remake sets the atmosphere that the Ishimura is on the brink of total obliteration by having an asteroid breach the hull of the Bridge.

Hammond Meets You Outside the Captain's Nest

Hammond will meet you outside the Captain's Nest, unlike in the original where he meets you inside. This gives a bit of time for the two of them to have a conversation about the Necromorph that attacked him.

Spacewalk and ADS Cannon Rework

The spacewalk outside the hull of the ship to the ADS Cannon has been reworked entirely. This time, Isaac only needs to calibrate 3 ADS Cannons as he traverses the spacewalk. Whit it was certainly tricky to complete the ADS Section in the original game, this version in the remake is more forgiving.

Chapter 5 Changes

Chapter 5: Lethal Devotion Walkthrough

Intentions Changed

In the original game, what prompted Isaac to go back to Medical was an oxygen level report read by Daniels stating that something was poisoning the air supply in Hydroponics. The chemical needed to devise a poison was located in Medical. However in the remake, what prompts Isaac to return to Medical was a seemingly broadcasted message from Nicole.

Corruption Tendrils

While it is largely the same, the setting that set up the initial part of the chapter is different. There are now corruption tendrils that have sprouted in various parts of Medical, giving a sense of the passage of time.

Initial Hunter Confrontation

In the original game, you are confronted by Dr. Mercer from behind the glass panel in the Chemical Lab. In the remake, this confrontation is a bit more personal because of the fake broadcasted message. Mercer puts Isaac in Stasis then releases the Hunter creating a more horrifiying encounter since you cannot move.

Lockdown replaces DNA Sample

After barely escaping the Hunter, Medical will be put into lockdown. Forcing you to lift the lockdown from Mercer's office. In the original game, you were supposed to get a DNA Sample of the growth poisoning Hydroponics.

A Reason to go to Hydroponics

After lifting the lockdown, Isaac gets information from a dying survivor that he must save Hydroponics from whatever was poisoning the air supply. Isaac figures out that the liquid nitrogen he needs is in Cryogenics.

Chapter 6 Changes

Chapter 6: Environmental Hazard Walkthrough and Wheezer Locations

No Direct Tram to Hydroponics

Unlike the original game that tells you of a nearby secondary Tram Station that will take you to Hydroponics, the path to Hydroponics will take you back to Tram Maintenance. From there the room at the far end will now be unlocked taking you to Hydroponics Tram Station.

Hammond No Longer Appears in Hydroponics

Because of the change in the narrative in Chapter 6, Hammond will no longer appear in Hydroponics. Instead you will be able to communicate with Dr. Elizabeth Cross. There she will guide you in the objectives of the chapter.

Similar Objectives, Different Executions

In the original game, you will be tasked to find 8 Poison Pods and kill them to purify the air. In the remake, you will still find 8 Necromorphs with similar character design but renamed as “Wheezers”. Instead of killing them directly, you are tasked to inject them with the enzyme to weaken the Leviathan.

Chapter 7 Changes

Chapter 7: Into the Void Walkthrough

Origin of the SOS Beacon

In the original game, it was Kendra that informs Isaac that there was an SOS Beacon in the Mining Deck. In the remake this is replaced by Dr. Cross telling Isaac that Jacob Temple and the other survivors were creating an SOS Beacon in the Mining Deck and that she hasn't heard from him in a while. Prompting Isaac to check out the Mining Deck.

Way to the Mining Deck

Again another change is how Isaac gets to the Mining Deck. To make the game more engaging, players will have to navigate from Hydroponics to the Rig Room and then an Elevator to Mining Operation. This is in stark contrast to the original game's directive of merely telling the player to return to the Tram Station and be taken to the Mining Deck automatically.

New Traps in Sub Deck C: Mining

There are new hazards present in the Mining Deck courtesy of the mining crew. This makes the entire exploration in the floor more dangerous for both you and Necromorphs.

The Hunter Reappears!

Fans of the original game will not be pleased to see another Hunter so soon. The Hunter is only encountered in Chapters 5 and 10 in the original game, so this is a sure surprise since you will be stuck in quarantine with an unkillable enemy locked in with you.

Chapter 8 Changes

Chapter 8: Search and Rescue Walkthrough

Comms Array Puzzle Change

Unlike the original puzzle, that only required a player to put all six nodes into the terminals, the Comms Puzzle in Chapter 8 now factors in the flow of the electricity that powers the antenna.

New Leviathan Remnant Boss Battle

Now there is no hull protecting Isaac as he pilots an ADS Cannon at the Remnant. This time he has to go outside and fight it in the vacuum of space. Making it a more tense fight since you have to watch your oxygen levels.

How to Beat the Leviathan Remnant (The Slug)

Boarding the USM Valor

They have completely scrapped the idea that you have to clear radioactive material before boarding the USM Valor. Instead you have to hover directly to the USM Valor.

Chapter 9 Changes

Chapter 9: Dead on Arrival Walkthrough

There's a Nuke On Board

An additional objective is triggered when you reach the USM Valor. You'll have to dispose a nuclear warhead before you can get the Singularity Core.

Shooting Gallery Trophy Changed

You no longer need to establish a high score in the Shooting Gallery to get a trophy and its rewards. You only need to survive the horde that will appear when you activate the shooting gallery.

How to Survive the Shooting Gallery: Front Toward Enemy Trophy Guide

Engine Room Reoriented

The old orientation of the engine room is that the flames will only fire in one direction, and you would have to destroy six plasma cells. In the remake, the fires will spray in different directions, and you would have to turn on the fire suppression system to proceed.

Hammond Gets Killed By Necro-Chen

Hammond is no longer brutally killed by a Super Brute. Instead, he will be killed by Necro-Chen. He also sacrifices himself and Necro-Chen to disable the Singularity Core for you to grab it.

Escaping the USM Valor is More Cinematic

The escape from the USM Valor is now more cinematic. Isaac has to run to the airlock as the USM Valor spontaneously combusts into a grand explosion.

Chapter 10 Changes

Chapter 10: End of Days Walkthrough

Entirely New Objectives

In the original, you only need to find navigation cards and then you will be able to fix the emergency shuttle. In the remake this objective is completely replaced to destroying tendrils in 4 locations to gain access to the Executive Shuttle.

Jacob Temple's Murder

Jacob Temple is now brutally murdered in stasis. You used to be able to step back and not watch Mercer kill Temple, but in the remake you lose control of Isaac and will have to watch the murder play out.

Chapter 11 Changes

Chapter 11: Alternate Solutions Walkthrough

Peng Treasure Location Change

The Peng Treasure is no longer located in the hangar bay. Instead it is found in the one of the lockers in the Cargo Bay as you transfer the Marker.
Where is the Peng Treasure?

Tendrils in the Cargo Bay

To make the whole Cargo Bay sequence distinct from the original game, tendrils were added in the Cargo Bay as an additional mini-objective for you to be able to transfer the Marker.

Chapter 12 Changes

Chapter 12: Dead Space Walkthrough

You No Longer Have To Drag the Marker

Much of the appeal of the last chapter in the original game was that you had to use Kinesis on the Marker and physically drag it to the pedestal site. Now that the marker is automatically pulled by the conveyor belt, it loses that sense of triumph in dragging it yourself.

Different Generator Room Design

The generator room that powers the tethers of the planet have also been reworked into a more open space instead of a tubular design.

Nicole Hallucination is Actually Elizabeth Cross

And finally we learn that the hallucination of Dr. Nicole Brennan is actually Dr. Elizabeth Cross, which explains how she was able to interact with the terminals in the Ishimura and how she was able to give Isaac assistance when he needed it.

A Secret Ending

It goes without saying that the inclusion of the secret ending is another game-changer for fans of the original game.
