Events of Dead Space 3Edit
The Armory is available in Chapter 11 after defeating the Snow Beast for the second time in the Staging Yard. Isaac Clarke notices a large amount of flares that were left behind at the entrance by Jacob Danik's Circle in an attempt to secure the weapons stored there. The player has the option to investigate the Armory to claim the weapons before Danik's soldiers do.
While exploring the Armory, Isaac will find a locked door, forcing the player to search for the key to get the munitions. Further exploration of the Armory and Isaac will find a small group of Danik's men searching for the key. Revealing Isaac's position to them will have them open fire, causing Feeders to attack both parties. After finding the key in the lower level of the same room, Isaac backtracks to the locked door and more of Danik's men are waiting for him beyond it. In a SK-1P station deeper in the Armory, Isaac will find a storage container guarded by two more of Danik's soldiers. After dealing with them and the Feeders that come soon after, Isaac opens and loots the container, completing the mission. The player then continues the story from the point they left off.
As soon as you go in the door towards the armory, you are greeted with a bench and a suit kiosk. There is also a small room here that looks like a security office. Inside is a Unitologist artifact. Once ready, take the elevator down. Deploy a scavenger bot near the tram. Then walk across the lobby towards the bench and take the other elevator down. You are now officially starting the side quest with the third bench in a row.
Continue through this room to a room with a bridge. Use Kinesis on the gate doors that are off to the sides, then kinesis to grab the items behind the gates. Included is an upgrade circuit and plenty of supplies. The next room has a couple enemies, a weapon part on a shelf on the left side of the room, and some more supplies to grab before going down an elevator. Go through the next room and into a more open room. There is a contact beam blueprint in the back behind some lockers. Now, go through the door labeled "Raised Hall." After fighting your way through the room, collect the loot and use the console to unlock the next door.
Go through the next room with the bridge followed by a room to deploy a scavenger bot. The door here reads "ordnance tower 02" and when you try to open it you will get a door malfunction and be attacked by several enemies. Kill the enemies and exit the door into a room with a bridge. Half-way over the bridge, a body falls from the sky and gets impaled on the railing. Strange. The next room has an upgrade circuit as well as an audio log. You don't have the key to go forward, so use the elevator in the room to go up. Walk out along the walkway and cue the suspenseful music. Take out the human and Necromorph enemies, then take the cargo elevator down. There is a weapon part on a crate, an audio log, and the armory key. After snagging the key, fight off the wave of Necromorphs, then go back down the elevator. Just before the locked door is a vent where an enemy will jump out at you. After dispatching this guy, use the key on the locked door.
You end up in a room that has a bunch of S.C.A.F. mining carts. Kill off the Necromorphs, then wrap around the carts to get to the door, after getting the Artifact at the back. You have to bypass security first, but once done go on through. In this new room, go straight across and you'll get a door malfunction again when trying to open the door. Fight off the wave of enemies that pop out. Once all dead, actually open the door and go through. Go down the hallway and take the elevator up. Now, hang a quick left and unlock the door with the key to go through. You are greeted with human enemies. Kill them, and cross the room. Go through the next room into the elevator at the end, and ride it up. Clear out this room, and then open up the chest. There are two weapon parts and a supply crate here. Now, go down the other elevator in the room, and then straight out to end the side quest.
