Dead Space Walkthrough

7. Story - Chapter 4

Chapter 4 - Obliteration Imminent

Your first task is to meet a NPC in the captain's nest on the Ishimura's bridge. Before you move on to the next area, take the contents from 2x wall containers in front of you and collect a Small Med Pack to your right. Enter the hallway to Main Atrium, grab the ammunition on the floor. Since it's a big area, it has lots of containers with items. Move counterclockwise to ensure that you don't miss any: 5x floor container, 3x ammunition. Most important item is the audio log (#22/150, "Initial Attack") in the far right corner. Keep an eye out for the Ishimura's circular emblem: blue background, red outline and 石村 (the ship's name). Use the stairs on either side to reach the cargo lift. Take it and gather Level 3 Suit schematic (#VIII/XVI). This pops:

Use the door to enter Captain's Nest. Empty 2x wall containers, stomp a green crate and collect a text log (#23/150, "List of Dead") before you return to Main Atrium. Keep left and head towards the Store (the same way you came to Captain's Nest). Buy the Level 3 Suit and stock up on Medium Med Packs, one or two Stasis Packs and ammunition. When you're set, re-enter Main Atrium, backtrack to the save station and make a save. Now you're set to explore the rest of Main Atrium. Make another save if you want before approaching a door left of the entrance. This spawns a new kind of Necromorph: a Brute. It's vital to use Stasis when it starts charging at you. Then either circle around the Brute to reach it's back and damage its legs until the Brute falls over or shoot off one of its arms. In doing so you rob the enemy of its ability to run. The Brute stays put and resorts to spitting organic bombs. Back off a few paces, catch one bomb with Kinesis once it pops out if its torso and throw it back to receive:

Later in the game you'll have another chance to get this achievement and it it will be mentioned in the walkthrough.

Other than that, it's a good way to save on Stasis packs and ammunition. Just keep catching and throwing until the Brute is dead which also unlocks:

Don't forget to pick up the Credits it dropped. Enter the room the Brute burst out of, grab a Power Node, then activate the console. The adjacent room has an Upgrade Bench, 2x lockers and a green crate. Keep at least one Power Node for an emergency supply room later in this chapter.

Resume your path and take the elevator to Ship Systems Level. Inside, grab a video log (#24/150, "Captain's Demise"). Step out of the elevator, loot the 2x containers (wall, floor) and stomp the green crate straight ahead. Continue, pick up a Contact Beam schematic (#IX/XVI) and enter SS Storage A. Be careful, as a Slasher is playing dead next to a Stasis Recharge Station. You know the drill. Empty 2x wall containers before leaving. Continue along the hallway to enter Ship Systems. As in the live audio message said, pay attention to the malfunctioning Gravity Panels. These can be used to your advantage. Either trick a Necromorph into stepping onto one of these or use Stasis and carefully push/melee the Necromorphs into the distortion field. Don't step on it accidentally yourself, it's an instant kill. Doing this five times nets you:

Force an enemy into a Gravity Panel 5 times

As a heads up: there'll be two more areas with Gravity Panels in this playthrough. It's highly recommended to get all kills in the first two areas as the last one requires lots of Stasis packs. Moreover, the enemies will be harder to handle.

On the right side of the warning sign is ammunition. Grab it before you continue. You encounter a Lurker which ends up smashed against the ceiling by a malfunctioning Gravity Panel. This is a scripted event and doesn't count towards the achievement.

Around the corner is a Slasher. Try to lure it to the plate. Once done, continue and you bump into another Lurker. Quickly use Stasis on it and push it into the distortion field. Turn around the corner for ammunition which in turn spawns a Slasher. Dispose of it, replenish your Stasis at the rechargy station in the previous area, if you need to and proceed towards your objective. You encounter two Lurkers - try to force both into a Gravity Panel. When both are dead, remove the crates blocking your way and move onwards. You trigger a Brute but it won't follow you, if you retreat to the nearby Stasis Recharge Station. Kill it as you wish: either by its own projectiles or unloading an ammunition clip. Make sure to grab the Power Node it drops plus 2x ammunition lying around.

Your given task is to activate a console but a few deadly electrified wires are blocking your way. Use Stasis and quickly run to the console. Before you start backtracking to Main Atrium, snag a Medium Med Pack on the other side of the room. Take care of two Slashers, make a save afterwards, then take the elevator. You get ambushed by two Leapers in Main Atrium as soon as you step outside. If you're still working on your Line Gun kills, try to group them and drop a timed mine on top of their heads with your secondary fire. When they're dead, another pair of Leapers spawns. Upon their demise a lone Leaper appears.

Stop by the Store if you need to, else follow your locator and use the elevator to Mining Admin and Comm Array Levels. Travel to level 01 and loot the 2x floor containers next to the save station before you enter the hallway to Mining Admin Room. There's ammunition outside the hull breach but it's hard to grab with Kinesis. Ignore it if you want. Head to MA Hall Storage and collect everything inside (locker, wall container). Resume your way to Mining Admin Room. A word of warning: this area is the last feasible opportunity in this playthrough to kill Necromorphs with Gravity Panels.

Head inside and you see two Enhanced Slashers. Deal with them as you see fit. If one got away, it's likely it won't return. Nearby is the only emergency supply room in this chapter, unlock it for goodies (e.g. a Gold Semiconductor). Depending on how close to your objective you are, a Lurker pops out. Don't activate the console yet. First we have some house cleaning to do. Grab all corpses on the floor with Kinesis and drop them onto a Gravity Panel. This will thoroughly remove all limbs from the corpses without stomping them yourself. Afterwards, look for a room named MA Storage B for a wall container. Leave and go straight to the end of the room towards MA Computer Room and head in. In front of a wall container is a text log (#25/150, "Report of Infection"). Head into the next area (MA Storage Room D) for a Power Node to your right as well as a floor container and a green crate. Return to Mining Admin Room and follow your locator to the objective. Activate the console, then nab the Small Med Pack to your right before backtracking. A lone Infector spawns and is desperately looking for a dead corpse to latch onto. Take it out of its misery and return to the elevator.

Travel to level 03. Grab a Force Gun schematic (#X/XVI), an audio log (#26/150, "Temple on the Bridge") and the contents from 2x containers (wall, floor). Continue while looting 2x wall container to your left and take care of a Pregnant and an Enhanced Slasher. Activate the console. Your new task requires you to travel to the ADS cannons. Continue and take a short detour to your right into the Storage Room 47 for a locker and a green crate. Resume your way and use the elevator leading to Ship Exterior Access. Collect a Medium Air Can before you step outside and onto the ship's exterior hull. Be careful, though: you'll get crushed to death by asteroids if you don't manage to hide behind a barricade once the storm starts.

Once outside in the vacuum, immediately run to the barricade straight ahead, not the one to your right. Look diagonally to the right and you see a tilted wall with two barricades. Wait until the wave passes and jump towards the barricade further away from you. Immediately run to the barricade behind it with the Oxygen Recharge Station. After another wave, jump back onto the floor. Try to jump as far as possible and hide behind a barricade. When the wave is over, continue running towards the door. Inside, grab the Ruby Semiconductor, stomp a green crate and make a save. DO NOT SIT DOWN until you made that save. One achievement wants you to survive the ADS cannon sequence with at least 50% hull integrity left. If the achievement didn't pop, you can easily load up your save.

This is one of the hardest achievements in the game. The spawns of asteroids is random. Sometimes you get lots of big chunks, sometimes none. Moreover, you can't change the control sensitivity. Don't feel discouraged though. Yes, it takes at least a dozen attempts but it's definitely doable. If you're getting frustrated, keep the save, move on and return later.

A few tips:

  • crank up your Brightness setting to the maximum to see asteroids early (cn_start > Options > Brightness)
  • turn off Vibration (cn_start > Options > Vibration OFF)
  • if a big asteroid appears, prioritise this over small ones
  • try not to overload your cannon, it will take away precious time
  • stay in the center

At some point the automated system will kick in and your job is done. If you managed to survive this minigame with at least 50% hull integrity, you receive

Reset your Brightness setting to the previous state and turn Vibrations back on, then backtrack to the tram station as you're told. When you go outside into the vacuum area, you bump into two Leapers. Either run past or kill them. Proceed onwards and you encounter a new kind of Necromorph. Actually, it's a Necromorph broken apart into its components. Deal with them as you like. Take the elevator to level 02 and continue backtracking to the tram station. On your way you run into two Slashers, one in front of you and another behind you. Proceed to enter the tram station. Activating the console inside the tram completes your objective and you receive:
