Modern Warfare 3’s SMGs are perfect for close-quarters combat and the WSP Swarm is a lethal option that players shouldn’t overlook. Before you drop into a match, here’s the best WSP Swarm loadout in MW3, featuring attachments, Perks, and Equipment.
Modern Warfare 3 is packed full of weapons for any situation, from all-around Assault Rifles to long-range Sniper Rifles. But, if you’re looking to dominate close-range fights, then you’ll need a deadly SMG to run around with.
Although old favorites like the Lachmann Sub are powerful once again after being carried over from MW2, most players will be looking to try out the new arsenal. Luckily, the new WSP Swarm has all the makings of a top-tier SMG.
