Shooting them in the body didn't seem to work. Go for the limbs, dismember them. That should do the job.

Technical Specifications

The CMS Greely is a Sovereign class research vessel that makes up one of the ships in the orbital flotilla around Tau Volantis.


Events of Dead Space 3Edit


The CMS Greely is a research vessel that is a location in Dead Space 3 when Isaac is venturing to the CMS Terra Nova to repair the CMS Crozier. When Isaac ventures outside of the CMS Roanoke he begins to pick up on a signal of unknown origin; a looping message mentioning a code "Papa Sierra". Jennifer Santos realizes that the signal is being generated from the Greely and then becomes an accessible location for Isaac.

Entering the Greely starts the optional mission. Upon venturing into the Greely, Isaac meets a problem, a security lockdown locking most of the doors and a power outage. After turning on the power, Santos tells Isaac that the lockdown originated from the Greely's radio room, and after disabling the lockdown, an audio log reveals what caused the power outage and security lockdown; a Doctor Barton was attempting to broadcast the coded message to Tau Volantis, but was caught by S.C.A.F. soldiers during the Scenario Five order. When the soldiers attempted to interrogate them, they locked themselves inside with the broadcasting equipment. Since the order was to ensure no one lives, they cut the power in order to disable life support and stop the broadcast. 

Upon further exploration of the Greely, Isaac finds a room with an overloading power generator and disabling it, overloading some of the gravity plating. Further investigation of the room will reveal a key and an audio log by a Laura Engstrom pleading for Barton to send the coded message to Dr. Serrano or all of their work would be destroyed. The key opens Engstrom's office, so Isaac decides to head for her office to decrypt the coded message. Because the power generator was disabled earlier by Isaac, some of the gravity plating was overloading on the way to Engstrom's office, making backtracking more difficult. Upon reaching the office, it is revealed that "Papa Sierra" meant "Hide Rosetta". When talking about it with Santos Isaac believed that the research involving "Rosetta" could be a key factor to the mission, which prompts Santos to question why issue the cleanse order if it meant destroying Rosetta, and Isaac figured that they either panicked or knew something the others didn't. Afterwards, Santos thanks Isaac for looking into the Greely and Isaac continues the mission at whatever the point the player left off.

Later in the chapter after Isaac goes to the Terra Nova he must venture back to the CMS Greely and salvage a port side engine from a dismantled shuttle. After getting the engine Isaac returns to the Roanoke and the Greely is left in orbit with the rest of the ships in the flotilla after Isaac and the other survivors launch the shuttle to the surface.

Spoilers end here.

  • The Greely seems to be the exact same model as the CMS Brusilov.
  • A scuttled Shuttle is near the Greely and the port engine is taken for the CMS Crozier .

he first Side Mission takes place at the end of Chapter 4. As you walk out of the Roanoke you'll receive a coded message being broadcast from the C.M.S Greely. Naturally, you get tasked to go and investigate. Fly on over to the transport ship and select the C.M.S. Greely. It's kind of difficult to locate the door to enter the Greely if you don't know what you're looking for. Using your waypoint will point you in the right direction. Other wise just look for the big letters on the side of the ship that say C.M.S Greely, the airlock is located on the left side of that.

Once inside the ship, Santos will be telling you where you need to be going. The first room you walk into there will be loot lockers on the left side, and a Compact Standard Frame on the right.

Go down the ladder into the main hub for the Greely. Since there isn't any power, every door is locked but one. You'll be attacked by one lonely Dog Lurker, take care of it, loot the few lockers in this area then head down the stairs by the windows.

The next area you'll find yourself in a engineering bay. There are a couple crates to loot, then head down the ladder to get to the generator. Use your Kinesis to power it on. This one is different from all the other kinesis doors you have to keep pressing the button to power it up rather than just holding it. Once the power is on, head back up the ladder. You'll be attacked by a couple Slashers and a Puker Necromorph, so dispose of them and leave the room through the door closest to vent shaft where the Puker came out.

Once in the radio room, go to the blue fuse box and start the mini game to balance the power. It's fairly simple but the combination is below in the picture. There is a couple things to loot here, stay and listen to the message that automatically starts play if you want, or leave this room through the lower door.

Back in the main hub you be attacked by a couple Slashers, a Puker, and an Exploder. After you've taken care of them, you can head over to the Bench that now has power and deposit your loot or head down the stairs that the first slasher came out.

The next room looks similar to the room the title screen is based on. Right when you enter the room you'll be attacked by a Puker and a few Dog Lurkers. There are a few things to loot here, including an artifact. Once you're done here head down the elevator.

The next set of rooms has a bunch of biohazard creates stored in them. There's a Slasher crawling on the ground behind one set right when you get off the elevator. Take it out and proceed around the room when you get to where the Slasher was crawling, another Slasher will come and attack you from where you just came from. Kill it and proceed into the next room. This next room has a handful of loot creates and a new creature type to the Dead Space cannon. They look like mini Head Crabs from Half-Life. These little Crabs will turn any corpse that still has it's limbs intact into Wasters or Slashers. Since there are no nearby corpses they'll come after you. They're easily disposed of with a pistol or a SMG, the plasma cutter doesn't do to well against them as it's a little slow firing off rounds. Once they're mush on the floor, turn the crank on the wall with your kenesis and open the door to the next area.

There are corpses all over the floor in this next room. It's a good idea whenever you see corpses you should stomp and remove those pesky limbs from them. Unless of course you like the unnecessary challenge and waste of ammo. Walk up the generator that causing all the electricity that's just so conveniently blocking your way. Use your kenesis on the panel with the kenesus symbol on it and walk just off to the side of it and pull on the panel with your other thumbstick. Take the Semiconductor and the machine will turn off. But now gravity panels are going to start popping out of the floor everywhere. Whatever you do don't walk on them, they kill you instantly, but they are great ways to kill Necro's. Head over to the blue panel and use your kenesis on it, a transmission will start playing informing you that the decoder is in the doctors room back at the Hub. Grab the key off the box on the other side of the blue panel and the Electric Charge weapon upgrade then leave this area. But before you can those crabs will come back. Unless you took care of those corpses on the ground they will do straight to them and turn them into Slashers.

As you backtrack to the main hub sections of the flooring will be blown off from the gravity surges, and you'll be attacked by waves of Slashers and a couple Pukers. A good idea will be putting the gravity panels between you and Necros, as the majority of them will just run right into the panels and kill themselves.

Once back in the hub, you'll be attacked by a small group of Exploders, just hang back in the stairwell and pick them off one by one. Go to the door that has a panel next to it near the Bench. Use the key and enter the room to get the decryption. You'll also find Tungsten in this room as well.

NOTE: If you save and quit or leave the Greely after hearing the decrypted message you will NOT be able to come back into this ship. When you load up your game again it loads you back at the transport ship and the airlock to the Greely will be locked. So if you want to use the Tungsten you found in the good doctors office to make a tungsten crank and open the last door in the hub now is the ONLY time you'll get to do so. I found this out the hard way and unfortunately don't know whats in that room.

Update: In the room, there is some ammo,a stasis pack, a telementy spike (used for crafting), and an upgrade circuit.

That being said leaving the Greely officially ends this side mission.
