Best WSP Swarm Warzone & Modern Warfare 3 Build

The WSP Swarm is an all-around great primary weapon for Modern Warfare 3’s Core Multiplayer. Sure, the range is quite poor, but players running and SMG build typically do not fight players at a distance. As the WSP Swarm is the only weapon you will need to use for this class for offense, consider taking a launcher like thePILAfor defense against killstreaks.

For Warzone 2, however, the WSP Swarm can serve as a great close-range support weapon. With this being the case, consider pairing the WSP Swarm with a weapon that is capable of competing in the long-range meta. Some of our top picks includetheBruen MK9,theDG-56,theTAQ Eradicator, andtheMTZ Interceptor.
