The best WSP Swarm loadout in MW3 has one of the fastest TTKs in the game, obliterating foes in 230ms at close quarters. Equipped with top-tier mobility, plenty of firepower, and a blistering fire rate, the WSP Swarm is the ultimate aggressive SMG in Modern Warfare 3.

However, to maximize the weapon's potential in multiplayer and truly push the gun to its limits, it's key that every attachment you use is optimized. So, let's rundown the best WSP Swarm loadout in Modern Warfare 3, so you have the chance of securing the prestigious nuke killstreak.

  • Muzzle: Shadowstrike Suppressor S
  • Stock: FSS Fortress Heavy
  • Magazine: 40 Round Mag
  • Rear Grip: Marauder Grip
  • Underbarrel: XRK Edge BW-4 Handstop

Kick off your loadout with Shadowstrike Suppressor S muzzle, which makes you undetectable by radar when firing your weapon. The majority of silencers come with heavy downsides, but this has no drawbacks so it's a must-use attachment.

Next, run the FSS Fortress Heavy stock and the Marauder Grip for a massive boost in recoil control. This makes the WSP Swarm a laser at close quarters and ensures every bullet will hit the target.

Following this, the XRK Edge-BW-4 Handstop is essential to bring your movement speed up a level and of course, the ADS time reduction will make you snappier when face-to-face with a foe.

Round off the setup with the classic 40 Round Mag to ensure you're always topped up on ammo and can clutch up against two opponents if needed.

Best WSP Swarm MW3 class: Equipment & perks

  • Gloves: Quick Grip
  • Boots: Lightweight
  • Gear: EOD Padding
  • Vest: Infantry


  • Lethal: Grenade
  • Tactical: Battle Rage
  • Field Upgrade: Munitions Box

Starting off with Perks, Quick Grip Gloves are highly recommended so you can swap to your secondary instantly, making it less likely for you to ever be caught off guard.

Next up, you can never go wrong with Lightweight Boots as the extra mobility is invaluable. Pair that up with the Infantry Vest for the added Tac-Sprint duration and you'll be a handful to deal with on any map.

Gear-wise, EOD Padding is a no-brainer as it protects you from non-killstreak explosives which are always some of the most frustrating deaths.

Equipment should be a Grenade for flushing out enemies from cover, Battle Rage for aggressive outplays, and a Munitions Box because running out of ammo is a problem no player wants to face.

How to unlock the WSP Swarm in MW3

The WSP Swarm won't be a fit for everyone, and if you find yourself a little lost with the pint-sized SMG, we suggest you pick up the Striker.

A true classic, the Striker is reminiscent of the OG UMP45 and the nostalgia hits even harder when you're running the weapon on the OG MW2 (2009) maps.

In our opinion, the gun is capable of solo-carrying matches and its consistency in every single gunfight is the weapon's biggest strength.
