All ’Crash Site’ weapon and item locations in MW3
The “Crash Site” mission in Modern Warfare 3 features 10 hidden weapons and item supply boxes scattered throughout the map, each offering unique gear to enhance your loadout. Players can find items such as the Silenced Victus XMR, Kastov 762, Heartbeat Sensor, Silenced Crossbow, Incendiary RAAL MG, Incendiary Lockwood 680, Armor Box, Silenced M4, Silenced SA-B 50, and Munitions Box. These supply boxes are located in various spots, including inside houses, beneath sheds, on rooftops, and along building walls, all concentrated around the main crash site area. Once discovered, these weapons and items become available for future loadouts, making exploration and collection essential for mastering the mission and unlocking achievements.

There are 10 weapons and items to find in the “Crash Site” mission.
1. Silenced Victus XMR

From the mission start on the east side of the map, head west-southwest past the water tower. After you crest the hill, you’ll see the Silenced Victus XMR in a small pavilion under a flickering light.
2. Kastov 762

Head west and into the house to the south of the titular crash site. In the front room, you’ll find an orange crate with the Kastov 762 inside.
3. Heartbeat Sensor

Head to the back of the house and loop around to the south side. You’ll find another crate with the Heartbeat Sensor at the southwest corner.
4. Silenced Crossbow

There’s another small pavilion just to the west between the tail section of the plane and the house. You’ll find the Silenced Crossbow inside.
5. Incendiary RAAL MG

Head north-northwest from the Silenced Crossbow and cross the street. You’ll find the Incendiary RAAL MG in another pavilion.
6. Incendiary Lockwood 680

Northeast of that pavilion, you’ll find another house. Hop through the window into the back room to find the Incendiary Lockwood 680.
7. Armor Box

Head north from the second house and cross the road to find another pavilion and another orange crate. This one has the Armor Box field upgrade inside.
8. Silenced M4

Head east-southeast toward the large silo and barn. You’ll find the Silenced M4 inside along the west wall.
9. Munitions Box

Continue southeast toward yet another pavilion to find the Munitions Box field upgrade inside.
10. Silenced SA-B 50

Back to the west, use the vehicle to climb on top of the low, flat-roofed building. You’ll find the Silenced SA-B 50 up there.

Where are the most hidden weapon spots on Crash Site in MW3
Some of the most hidden weapon spots on the “Crash Site” mission in Modern Warfare 3 are tucked away in less obvious locations, making them easy to miss if you’re not thorough:
-
Silenced SA-B 50: Found on the roof of a small house in grid F4. To reach it, you need to climb onto a small white truck parked along the eastern side of the building-an unusual and easily overlooked route.
-
Silenced Crossbow: Hidden beneath a small shed in grid C5, not far from the tail-end of the plane wreckage. The shed’s location and proximity to debris make this supply box particularly easy to miss.
-
Incendiary RAAL MG: Located just southwest of the house with the Lockwood 680, this weapon is in a supply box beneath a small shed in grid D4, blending into the environment near other structures.
-
Heartbeat Sensor: Placed along the southern wall of a building in grid E5, directly east of the Silenced Crossbow and beside a large white truck. Its placement against the wall and near a vehicle can make it hard to spot in the heat of combat.
These locations are among the most hidden due to their vertical placement, camouflage with environmental elements, or positioning near similar-looking objects and structures.
Which hidden spots on Crash Site offer the rarest weapons in MW3
The most hidden spots on “Crash Site” that offer the rarest weapons in Modern Warfare 3 are:
-
Silenced Victus XMR: This sniper rifle is tucked under a small overhang to the left of the main road, near the mission start, before the first house with enemies. Its location is easy to miss due to the overhang and the lack of immediate combat in the area, making it one of the rarest finds.
-
Silenced Crossbow: Found west of a small house, past a white truck, inside a shack with flashing lights. Its placement away from the main path and inside a nondescript shack makes it a rare and easily overlooked weapon.
-
Incendiary RAAL MG: Located north of the crossbow spot, directly west of the burning plane, in another shack. This heavy weapon’s location, hidden among wreckage and not directly in the main line of sight, adds to its rarity.
-
Silenced SA-B 50: Positioned on the roof of a small house in grid F4, accessible only by climbing a white truck parked along the building’s eastern side. Its vertical placement and the extra step required to reach it make it one of the most hidden and rare weapon spots on the map.
These locations stand out for their combination of concealment and the unique or powerful nature of the weapons they hold, making them the rarest and most rewarding finds on the Crash Site mission.
