Reactor 02 Control Room is a Rare key in MW4 DMZ. It opens the control room inside the round Reactor 02 building at Haneul Nuclear Reactor, grid H4, deep in the radiation zone. Behind the door is a long, dark control room full of computers and lockers. Below is where the door is, how to get there and what we found inside.
- The door is on an upper floor inside Reactor 02 at Haneul Nuclear Reactor (H4), at the top of a dark stairwell.
- Reactor 02 is in the radiation zone and was a High threat area in our run, so bring a gas mask or a hazmat suit.
- 20 containers, with six computers and four military lockers, and three Legendary Hazmat Suits hanging on the wall.
- Worth it when you are at the reactor anyway, for example for a mission: the three Hazmat Suits let you stay in the radiation zone much longer.
Where the Reactor 02 Control Room Door Is
The Reactor 02 Control Room is inside the round Reactor 02 building at Haneul Nuclear Reactor, grid H4. The door is on an upper floor at the top of a dark stairwell, a grey door that is easy to miss in the gloom. The whole area is inside the radiation zone and was a High threat area in our run. You can also find the door under the keys layer on our interactive MW4 DMZ map.

How to Get the Reactor 02 Control Room Key
The Reactor 02 Control Room key is field loot, so it can drop from ordinary containers on Hajin. Ours came out of a duffel inside the Commandant Office at Chang-san Air Base. Every other key and the door it opens is in our MW4 DMZ keys guide.
The Route to the Door
- Put on a gas mask or a hazmat suit and come in from the north shore of Haneul Nuclear Reactor, heading south through the radiation fog.
- At Reactor 02, climb the pipe up the wall onto the ledge, then follow the building around past the rubble to the entrance.
- Go in and take the dark stairwell up. The grey door at the top is the Reactor 02 Control Room.
What Is Inside the Reactor 02 Control Room

From one opening in our own run. Loot is random, so your room can roll differently, and we add every new run of this key. Values are per item, from the in-game tooltips. The carried out value is the change in the loadout value the game shows while you loot.
Most of the room is crafting resources and gear. The computers give a steady stream of Electronics, Synthetics and Metals with Control Units and Detonators, and the military lockers hold armor plates, 2-Plate Armor Vests and a Medkit. Our best valuables were Degraded Execution Footage in one of the crates and Nuclear Program Files in a computer. Three Legendary Hazmat Suits hang on the wall just inside the door, which is handy if you came in on gas masks.

Is the Reactor 02 Control Room Key Worth It?
Only if you are already at the reactor. It is a very handy key when you have a mission there, because the room gives you three Hazmat Suits, exactly what you need to stay in the radiation zone for longer. On its own the loot is mostly crafting resources and armor, so it is not worth a trip just for the containers.
