Infinity Ward has changed how players kit up and customize gear for missions in the Call of Duty: Modern Warfare 3 campaign. Featuring Open Combat Missions that function similarly to Warzone or DMZ, players will have to find and scavenge equipment from around the mission area to add the weapons and equipment to the mission arsenal. Once a weapon, field upgrade, or tactical equipment is found, the item will become permanently available at the start of the campaign mission when creating a loadout. These items transfer across difficulties as well, meaning players can go through on Recruit or Regular difficulty and find all the supply crates to have the weaponry available on a later replay on Hardened or Veteran difficulty. <img src="https://burst.shopifycdn.com/photos/preparing-for-travel.jpg?width=746&format=pjpg&exif=0&iptc=0"; style="max-width:440px;float:left;padding:10px 10px 10px 0px;border:0px;" alt="" />

All 29 weapon supply crates in the mission Reactor can be found before entering the reactor area of the mission, and players can use the spotter scope to tag crates and mark their location permanently.

The first crate players can find is on the far left edge of the mission map in the building in A-2 that only has one door that is stuck and cannot be opened from the outside - the crate can also be seen from outside the building through a metal gate making it easy to find the correct building.

There are only a few enemies guarding this building; take them down and make your way to the roof to find an entry point inside. Open the crate to find a Silenced Holger 556 , an assault rifle with a mid-long range thermal scope.

Another crate can be found on the roof of the large warehouse in B-2 . There is no ladder or stairs to access the roof, but players will find an ascension line on the south end of the warehouse. Ascend the line to find the box; players will find an Incendiary MCW assault rifle inside.

Players will find another supply crate in C-5 in the mid-level of the concrete building. Search the Southeast corner to find the crate that will add an Incendiary Sakin MG38 to the arsenal.

A crate can be found at the top of the radio tower in C-6 . Players can find a KV Inhibitor sniper rifle in this crate - the rifle has a variable zoom but is not suppressed and will alert enemies when fired. This tower is a great location to use the spotter and tag enemies and supplies to your map - remember, tagged supply crates will have their location saved on the tac-map.

The next crate players can find is at the top of the circular stone structure in D-4 near the first Konni Helicopter that needs to be destroyed.

Use the wooden slats to climb to the top of the structure and find the supply crate on a ledge to the left . This crate will give players a Silenced COR-45 , a semi-automatic pistol with a reliable rate of fire.

A crate will be found in D-6 inside the fire station garage . There are several enemies guarding this area - approach the fire station from the south , climb in through one of the windows on the first floor, and take down the first enemy in the hallway .

Then, climb through the next window into the firehouse garage and take down the two enemies near the laptop . Once all enemies are down, find the supply crate to the right of the table with the laptop and open it to find a Snapshot Pulse .

Players can find another supply crate in the fire station at D-6, but first will have to climb to the very top of the building to unlock the area where the crate is located. Climb to the roof and take the stairs to the second roof level. Climb the crates up to the third level and climb through a window into the belfry - there will be a grate in the floor and a grenade beside it.

Look down into the hole to see an explosive barrel and a chair stuck under a door handle. Use the grenade or the explosive barrel to destroy the chair and unlock the door below . Players will want to jump out one of the windows on the West wall and descend to the first floor.

Climb back into the fire station through a window, and the locked area should now be available on the right. Players will find a large collection of armor plates and ammo in this room, along with the supply crate that will add a Minigun to the mission arsenal.

The next crate will be found in E-2, on the roof of the large warehouse near the electrical generators. There are ascension lines on both ends of the warehouse to get to the roof - players will find a Sidewinder assault rifle with a hybrid sight that switches between a thermal scope and a canted reflex sight.

On the north end of the circular compound in E, on the border of 3 and 4, players can find another supply crate. Climb to the very top of the stairs inside the circular area and find the supply crate on a metal platform near an ascension line. Opening this supply crate will add a Heartbeat Sensor to players' arsenal for this mission.

There is one more supply crate in the circular compound on the second floor Northwest corner in E-4 . Right beside the zipline, players will find the crate with a Silenced Expedite shotgun inside.

The next crate will be found in G-2 in an office building that has one room accessible, but the innermost room is locked. Players will be able to see the weapon supply crate inside the room from one of the windows but will have no points of entry from the first floor.

Use the truck nearby to climb to the roof and drop into the locked room through one of the skylights . The supply crate will be available on a couch and will give players a Basilisk revolver with armor-piercing ammo .

Just north of the reactor on the border of G and H and 3 and 4 on the grid map, players will find an armory with a supply crate. Players can stock up on ammo and supplies and open the supply crate to grab an Anti-Armor Rounds field upgrade .

There is a supply crate in the compound by the Konni helicopter in H-3 . Clear out the compound and find the crate directly West of the helicopter's position . This crate will add a Hybrid STB 556 assault rifle to the arsenal, with a high-powered scope and under-barrel grenade launcher attached.

Players will find a second crate to the Southeast of the helicopter in the open compound area that will give players a PILA launcher.

Players can find two supply crates side by side in the center channel of the compound in E-5 . There will be at least 6 or 7 enemies guarding this compound, as well as a sentry turret on the south end of the lane where the crates are located.

If players have a stun stick, they can throw it on the sentry turret to disable it after a brief delay. In these two crates, players will find an HCR 56 assault rifle with a holographic sight and an Incendiary Haymaker semi-automatic shotgun with dragon breath rounds.

Players will find another supply crate in this compound just to the East in F-5 . Head upstairs and look along the East ledge, looking towards the reactor . Players will find the supply crate with a Munitions Box inside.

There is a supply crate on the roof of the building of F-6 right beside the loadout crate. There is a ladder on the West side of the building that players can use for roof access - inside the supply crate, players will find a Silenced Vel 46 SMG .

There is another supply crate inside the building. However, both entrances are stuck, with no entryways through the roof. To get inside this building, <a href="https://Fpsshooter.com/">FPS game tips</a> players will have to find a window that looks inside the room and toss a grenade or shoot at one of the chairs, preventing the doors from opening.

Once the chair is destroyed, players can enter the room and open the supply crate to add the Armor Box to the Reactor mission arsenal.

Players will find another crate in D on the border of 4 and 5, right behind the first Konni helicopter. Take out the helicopter and <a href="https://Fpsshooter.com/">fps Shooter Official</a> surrounding troops and move in to open the crate. This supply crate will add the RGL-80 grenade launcher to the mission arsenal.

There is a crate in G-4 on the back of a cargo truck - this supply crate will give players an Incendiary MTZ Interceptor , a semi-automatic marksman rifle with a holographic sight.

On the Northwest corner of the roof of the reactor in the G-4 building, players will find another supply crate that will add the Explosive Crossbow to the mission arsenal.

On the roof of the compound just South of the reactor building in G-6 , there is a supply crate on the south side facing towards one of the Konni helicopters. This supply crate will give players a Signal 50 sniper rifle with a variable infrared scope.

Inside the building just south of the reactor in G-6, players can find another supply crate that will award an Incendiary Bryson 800 shotgun . To find this crate, head north from the Konni helicopter in G-7 towards the LTV with the sentry gun on the back.

Dodge the sentry gunshots and head to the right past the front of the vehicle and through the double doors on the south side of the building in G-6 . Right inside the double doors, players will find the supply crate.

From this crate, head through the door to the right towards H-6 and find another crate with a Silenced Lachmann Sub inside.

Players will find two crates side by side in 7 on the border of F and G , behind one of the Konni helicopters . Once the area is cleared, players can access the crates to add a Cronen Squall, an assault rifle with a hybrid holographic/thermal ACOG scope, and a Holger 26 LMG to the mission arsenal.

There is a crate at the top of the crane in F-5 - players can get here immediately after deployment into the mission by pulling the parachute as soon as available and gliding to the crane. The crate will be found in the middle of the upper railway - open the crate to add an Incendiary FJX Imperium sniper rifle to the arsenal.

Players will now have several options for weaponry to select when dropping in to replay the mission Reactor. <img src="https://burst.shopifycdn.com/photos/dice-games.jpg?width=746&format=pjpg&exif=0&iptc=0"; style="max-width:440px;float:right;padding:10px 0px 10px 10px;border:0px;" alt="" />
