Dead Space 3 Walkthrough Part 11 – Side Missions: C.M.S. Greely (Air Lock to Comm Room)

Once Issac can access the Skiff, “SK-1P” then he can start to move around the flotilla. Here he will find a quick and easy passage over to the C.M.S. Greely. He can find a number of different weapon parts here, some circuits, and artifacts. To get there, travel to it via the skiff. Once there, look for the designation and go just to the left of it. There Issac can find the air lock that will let him get in. If he lingers outside too long there is a good chance he will be attacked by a pair of Lurkers.

Once inside the Greely and have gotten from the airlock into the first time, Issac will talk with Santos again. In this first room there is a Suit Kiosk to the left. The kiosk is powered down, as most of the ship seems to be. To the right on the bottom shelf of the cart the far side of the ladder is a Compact Standard frame.

With those items grabbed, head over to the ladder and take it down. As Issac touches down from the ladder he will be attacked by a Lurker. Take a little time to search the area to find the various lockers  Until Issac gets the power back up, he can only explore this room and the one down the stairs. When you have looted everything on the upper level, head on down the stairs. At the base of them, to the right is another pair of lockers to loot. After that go to the left and down the hall to start toward Life Support.

Head on through to the next room. When Issac arrives in the next room with a ladder he will want to explore beyond it first to get some loot. After that he should head on down the ladder to the level below. Here he will find a pair of lockers. Behind them sits a generator. Using Kinesis he can activate it. Just be sure to hold the Kinesis button while the generator spins up. After that, he will contact Santos and she will set his waypoint to the Radio Room where the lockdown is originating.

Head on back up the ladder. This time in the Generator room, Issac will be attacked by 2 Slashers. Quickly take out their legs and kill them. There is also a Puker in this mix that will attack after the Slahers. Quickly take it out as it has a ranged attack. Head first to the left of the ladder and take the elevator up. This will take him straight to the radio room. Before going through the door to the radio room, take a little time to loot the lockers in this corridor. After that go on through the door.

Inside the Radio room, go around the outside of it to find a few lockers. After that, turn Issac's attention to the Blue lined Fuse Box that sits nearby the stairs going down. Issac needs to balance the power between the Lights and CPU to progress. From top to bottom:
