Reactor is the second Open Combat Missions and features the most amount of Weapons, Field Upgrades, Armaments, and Plate Carriers to discover in the game. If you’re striving for the Platinum Trophy, then you’ll need to collect all of these for the Gearhead Trophy/Achievement.
All Reactor Field Upgrade Locations
There are a total of five field upgrades stored in small orange supply boxes scattered around the Reactor map which include Anti-Armor Rounds, Armor Box, Munitions Box, Snapshot Pulse, and Heartbeat Sensor.
Where to Find The Snapshot Pulse in Reactor
The Snapshot Pulse will reveal the locations of nearby enemies and it can be found by opening up your map and heading over to the south to find an entrance to a garage containing Fire Engines.
Where to Find The Heartbeat Sensor in Reactor
The Heartbeat Sensor will allow you to see if there are any nearby enemies above or below your current location. It can be found by opening up your map heading over to the circular building in the center of the map, and then making your way up the stairs to find the supply box sitting beside the yellow fence.
Where to Find The Anti-Armor Rounds in Reactor
The Anti-Armor Rounds will allow you to temporally deal extra damage to armoured enemies and it can be found by opening up your map and heading over to the small garage in the northwest.
Where to Find The Munitions Box in Reactor
The Munitions Box does literally what it says on the tin and fully restores your ammo which is extremely useful in Open Combat Missions as you’ll be coming across a lot of enemies. It can be found by opening up your map and heading up to the rooftop of the building to the southeast of the circular building in the middle of the map.
Where to Find The Armor Box in Reactor
The Armor Box is another useful piece of field equipment for Open Combat Missions, as you’ll be able to throw down some Armor Plates on the floor and equip for extra health. It can be found by opening up your map and heading into the small blue and white office building to the southeast of the circular building.
