Discover the exact locations of the Heartbeat Sensor, Armor Box, and Munitions Box field upgrades in Call of Duty: Modern Warfare III's Crash Site mission. Get them fast!
Alright, so you're on the Crash Site map in Modern Warfare III and looking for those handy Field Upgrades? Don't worry, this map isn't huge, so there are only three to track down. You'll find these in the smaller orange supply boxes, not the big weapon ones. Let's get you kitted out!
Heartbeat Sensor Location
First up, the Heartbeat Sensor. This thing is a lifesaver for spotting enemies nearby, even through walls or floors. To find it, pull up your map and head to grid coordinate E5. Once you're there, just look behind the main building. You'll spot a small supply box tucked away – that's where your Heartbeat Sensor is waiting.
Armor Box Location
Next, we've got the Armor Box. This is super clutch for those bigger Open Combat Missions because it lets you drop extra Armor Plates for yourself and your squad. Open your map and make your way to grid coordinate E3. When you get there, you'll find a small wooden hut. Inside that hut is a small supply box holding the Armor Box.
Munitions Box Location
Finally, the Munitions Box. Running out of ammo in these long fights is the worst, right? This box refills your ammo completely. To grab it, check your map and head to grid coordinate F4. You'll find another small wooden hut, this one sitting right next to the cliff. Inside, you'll find the small supply box with the Munitions Box.
