Reactor DRC Locker is an Ultra key in MW4 DMZ. It opens the DRC locker that lies under water in the pool of the reactor hall at Haneul Nuclear Reactor, grid H4. The locker itself is an Elite Weapons Locker. Below is the route up the reactor building, how to find the locker in the water and what we found inside.
- The locker lies on the bottom of the pool in the reactor hall at Haneul Nuclear Reactor (H4).
- Ladders up the outside of the building, across the roof to the door with the Nuclear Reactor 1 sign, then dive into the pool.
- The reactor was a High threat area in our run and sits in the radiation zone, so bring protection.
- An Elite Weapons Locker with an Ultra Large Secure Backpack, an Epic rifle, a weapon manual and Nuclear Program Files in our run.
Where the Reactor DRC Locker Is
The Reactor DRC Locker lies under water in the pool of the reactor hall at Haneul Nuclear Reactor, grid H4. The HUD names the spot Reactor 02, and the door you come in through has a Nuclear Reactor 1 sign next to it. The yellow DRC locker stands on the bottom of the pool, so you have to swim down to open it, and it is easy to miss in the dark water. The reactor was a High threat area in our run and is inside the radiation zone. You can also find it under the keys layer on our interactive MW4 DMZ map.

Plus 5 items we could not identify.
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 loot value adds up every item with a known value and the cash, so it is a lower bound: crafting resources and items without a value are not in it.
Our locker held an Ultra Large Secure Backpack worth $15,000, an Epic assault rifle with four attachments, a weapon manual and Nuclear Program Files. Structural Alloy, Rigid Synthetics, a Concussion Grenade and a stack of three Rare pouches filled the rest.

Is the Reactor DRC Locker Key Worth It?
Yes. You do not have to get far into Operation Fallen Ember to reach the locker, and you can even get there without starting the mission, although the mission gives you the best spawn to get there fast. The loot is good, as we are used to from DRC lockers, with an Ultra backpack, an Epic rifle and a weapon manual in ours. The hard part is the key itself, which is rare and difficult to get.
