Modern Warfare 3's Highrise Mission: Your Complete Guide to All 19 Hidden Weapons and Items

This definitive guide reveals all 19 hidden weapons and items in Modern Warfare 3's challenging Highrise Open Combat Mission, helping you loot the map clean.

Alright, folks, gather 'round. Let me tell you about my latest adventure in the Modern Warfare 3 campaign. As of 2026, this game still has secrets that keep us coming back. I recently dove headfirst into the 'Highrise' Open Combat Mission, where I played as Gaz, storming a Konni safehouse in Saint Petersburg alongside the legendary Captain Price. Now, let me be real with you—this mission is a maze. A beautiful, chaotic, multi-story maze where you can easily miss the good stuff. While you can blast through the main objectives, the real challenge, and the real fun, is hunting down all 19 hidden weapons and items scattered like Easter eggs across the map. Trust me, finding them all without a guide is like trying to find a specific grain of sand on a beach. So, based on my own sweaty-palmed exploration, here's your definitive, no-nonsense guide to looting Highrise clean.

The Fifth-Foor Arsenal: Your Starting Point

This floor is where the party starts. Forget the main path for a second; the goodies are tucked away in the corners.

  • Silenced TAQ-M: This marksman rifle is your first big find. From the ground floor elevator shaft, climb to the top, grab some Night Vision Goggles (don't leave those!), and take a right. Navigate past the traps—watch your step!—until you hit a staircase. Instead of going up or down, duck down the hallway to your right. Boom, there it is.

  • Snapshot Pulse: From that same elevator shaft top, this time go left. The first door on your left leads to a corridor that ends in a tiled area. This handy tactical gear is just sitting there, waiting to reveal those pesky campers.

  • .50 GS & Silenced COR-45: A two-for-one deal! From the tiled Snapshot Pulse room, move into the next area. You'll see a locked gate with Supply Boxes. Hang a left, go to the end of the hall where you'll find a stairwell... but ignore it. Turn right instead, and in that next room, you'll find this powerful pistol duo ready for some close-quarters action.

Venturing Outside: The Scaffolding Shuffle

This is where things get vertical and a little... breezy. Exiting the building opens up a whole new playground.

  • Silenced Expedite 12: Found on the first floor, but you access it from outside. From the fifth-floor stairwell (near the TAQ-M), hop out the window to the right. Grab the ladder, go right, and carefully work your way down the scaffolding all the way to the bottom. Before you climb the next ladder out, check the cubbyhole on your right. A nice, quiet shotgun for those surprise encounters.

  • Explosive Crossbow: Also on the first floor, and oh boy, getting this one is a trip. From that same fifth-floor stairwell window, take the first ladder on the right. Then, mantle onto the box nearby. This next part requires a leap of faith—jump from that box through the open window directly opposite. You'll land in another stairwell. Just... jump down, pop your parachute, and float gently to the bottom where this beast of a weapon awaits. Feels like something out of an action movie, I'm telling you.

  • Incendiary MCW: The easiest find of the outside bunch. Once you have the Silenced Expedite 12, just walk past the exit ladder. There's a small room immediately to your right, and this fiery assault rifle is inside. Simple.

Reaching for the Sky: Floors Six, Seven & Eight

The higher you go, the better the loot... and the longer the fall.

  • Silenced Kastov 762 & Minigun: Let's talk about these two together because their paths are intertwined. Both are found by starting from the bottom of the outside area (where you got the Expedite 12). Climb the first and second ladders. You'll reach a sixth-floor balcony. From here, you need to jump across a gap to an open window.

    • For the Kastov 762 (7th Floor): Successfully make the jump into the window. You'll be in a blocked stairwell leading up to a room where this hard-hitting rifle is stored.

    • For the Minigun: Make the same jump into the window. But instead of going up the stairs, turn around and look down the massive stairwell center. Just... jump. Deploy your chute and enjoy the ride down. At the very bottom, you'll be greeted by the glorious, brrrrrrt-worthy Minigun. A bit dramatic, but totally worth it.

  • VEL 46 (8th Floor): Back to the fifth-floor stairwell and that trusty right-hand window. Climb the ladder outside, but this time, go left and head straight forward into the building on the seventh floor. Look for an opening in the ceiling. Go through it, and in the room to the right, you'll find this slick SMG.

  • Silenced MTZ Interceptor (7th Floor): To get this precision tool, first get to the eighth floor (using the path for the VEL 46). From the ceiling opening, go to the right side of the area (skip the ladder). Follow the hallway to the very end, where you'll find an elevator shaft. Don't call the elevator—just head down the shaft itself. The Interceptor is sitting pretty on a ledge right opposite where you land.

Final Thoughts & Pro-Tips

Phew. After combing through every floor, inside and out, I finally had my collection complete. Here’s what I learned:

Item Category Key Locations Pro Tip
Sniper/Marksman TAQ-M (5F), MTZ Interceptor (7F) Use these to clear rooftops and windows before moving.
Close Quarters Expedite 12 (1F), COR-45 (5F) Perfect for the tight, indoor hallway fights.
Heavy Hitters Minigun (Bottom), Explosive Crossbow (1F) Save these for scripted enemy vehicle or reinforcement moments.
Tactical Snapshot Pulse (5F) Invaluable for checking corners in the building's labyrinthine interior.

Navigating Highrise is about mastering its verticality. The outside scaffolding and interior stairwells are highways to loot if you're brave enough to use them. And always, always have your parachute ready. You never know when you'll need to make an impromptu exit.

So there you have it. Nineteen pieces of gear, one chaotic mission. It's a grind, but the feeling of being fully kitted out with unique, silenced, and explosive weaponry before the finale? Priceless. Now get out there and loot that place dry, soldier. I'll see you on the exfil.
