MW3 best WSP Swarm loadout for Warzone and Multiplayer

Update: With the release of MW3 Warzone, the WSP Swarm has found a new place as one of the most popular secondaries in the meta. We've updated this page with a new loadout detailing its varied use cases.

Modern Warfare 3 is packed with weapons to choose from, but as ever, the best weapons are already standing out from the crowd and being picked apart by COD pros and players.

While the most impressive weapons are locked behind levels and Armory Unlock challenges, there are still plenty of great guns to be experimenting with.

The best MW3 WSP Swarm loadout is for players who like to be fast. With an unholy rate of fire, you’ll be able to run and gun to your heart's content with this piece of kit. Here’s our WSP Swarm loadout, with all attachments, gear, and equipment you could need.

Best WSP Swarm Warzone loadout

Because of its ubiquity there are actually many different ways you can build out a WSP Swarm in Warzone.

• Muzzle:Spiral V3.5 Flash Hider or Lacerta Compensator or Bruen Cubic Compensator
• Barrel WSP Reckless-90 Long Barrel or MK.3 Reflector Optic
• Stock: FSS Fortress Heavy Stock
• Magazine: 50 Round Mag
• Underbarrel: Bruen Heavy Support

The first question you want to ask yourself when building a Warzone loadout for the WSP Swarm is whether you can deal with the iron sights or not.

YouTuber TheKoreanSavage uses the MK.3 Reflector to give them a precise and clear dot to work with at the expense of a barrel attachment. If you do use a barrel instead though, the WSP Reckless-90 Long Barrel is the one to go with, because it increases bullet velocity while also dealing with some kick.

The most loadout variation then comes in the Muzzle slot, with different players preferring different attachments.

TheKoreanSavage uses the Bruen Cubic Compensator because of its superior reduction to horizontal recoil, feeling that they can deal with vertical recoil more easily. On the same vein, BennyCentral uses the Lacerta Compensator for even more horizontal recoil reduction, however this comes at the cost of ADS speed. If you like to hipfire, try the Lacerta, otherwise go with the Bruen Cubic.

YTLukeyy on the other hand uses the V3.5 Flash Hider for general recoil control, while Cbass uses the L4R Flash Hider. This attachment boosts recoil control massively, at a slight detriment to ADS speed, which is no problem whatsoever for the WSP Swarm.

Because the WSP Swarm is so fast anyway, many streamers and pros use heavy stocks and long barrels to reduce recoil. There is consensus that the FSS Fortress Heavy Stock, which gives a big boost to kick and recoil control while trading off ADS and Sprint-to-fire speed, is the best option to go for.

This is all while the Bruen Heavy Support Grip is great for further eliminating horizontal recoil and keeping your shots locked to an enemy.

While a 100 round drum is available, you don't want to compromise your speed too much. This means there's also consensus that the 50 round mag is the best all-around option.

MW3 best WSP Swarm perks and equipment

Now that our WSP Swarm loadout is established and we’ve got a super-fast SMG in our hands, it’s time to run through what equipment compliments the weapon.

• Secondary Weapon: COR-45 or Renetti
• Vest: CCT Comms Vest - provides four gear slots and one equipment slot. Lethals and Tacticals are removed. Engineer Vest is a good alternative.
• Gloves: Scavenger Gloves - allows you to resupply ammo and throwing knives from dead players.
• Boots: Lightweight Boots - increases movement and swim speed
• Gear: Bone Conduction Headset - reduces combat noise, so you can hear enemy footsteps and gunfire more clearly. This can easily be swapped out for any other gear that you think will keep you alive for longer.
• Gear 2: Ghost T/V Camo - blocks detection by UAVs, enemy radar sources, and Heartbeat Sensors while moving. EOD Padding is a good alternative.
• Field Upgrades: Munitions Box or Trophy System - you can never go wrong with more ammo, but the Trophy System can destroy nearby equipment and projectiles.
