The launch of Call of Duty: Vanguard Season One saw the debut of Warzone Pacific and the highly anticipated Caldera map. Also, the integration saw the weapon pool expand and add even more weapons to choose from. So far, the MP40 has been the front-runner in the secondary weapon meta. However, there are plenty of other powerful submachine guns to choose from. One option is the Type 100, and applying the best attachments will allow you to build a dominant class to take to your next Warzone Pacific match.
