Reactor Field Upgrade Locations in MW3

Discover all five Field Upgrade locations in the MW3 Reactor mission: Snapshot Pulse, Heartbeat Sensor, Anti-Armor Rounds, Munitions Box, and Armor Box.

Alright, so you're playing through the Reactor mission in Modern Warfare III and need to snag those sweet Field Upgrades? No worries, I've got your back. There are five in total, hidden in little orange supply boxes. We're talking Anti-Armor Rounds, Armor Box, Munitions Box, Snapshot Pulse, and the Heartbeat Sensor. Let's find 'em!

Snapshot Pulse Location

First up, the Snapshot Pulse. This bad boy lets you see enemies through walls, which is super handy. Open up your map and head south. You're looking for a garage that has some fire engines inside. That's where you'll find the supply box.

Heartbeat Sensor Location

Next, the Heartbeat Sensor. This one shows you enemies above or below you. Again, pull up your map. Go to the big circular building right in the middle of the map. Head up the stairs there, and you'll see the box chilling next to a yellow fence.

Anti-Armor Rounds Location

Need to deal with those tough, armored enemies? The Anti-Armor Rounds are your best bet. Check your map and make your way to the northwest part of the map. There's a small garage there; that's where you'll find these rounds.

Munitions Box Location

Running low on ammo? The Munitions Box fully restores your ammo, which is a lifesaver in those big Open Combat Missions. Look at your map and head to the southeast of that central circular building. You need to get to the rooftop of a building there to find this box.

Armor Box Location

Last but not least, the Armor Box. This is another must-have for Open Combat Missions, letting you drop armor plates for extra health. For this one, check your map and head to the southeast of the central building again. Look for a small blue and white office building; the Armor Box is inside.
