Quick Links
Call of Duty: Modern Warfare 3is wrapping up its fourth season with a select few conversion kits that are tied to the Weekly Challenges system. Each week has 21 associated challenges to complete. Finish any five of them, and you’ll walk away with a new conversion kit or weapon outright.
This week’s reward is a conversion kit for the Basilisk, an MW2 revolver that turns into a .357 magnum. Fans of fast-firing secondaries might want to give this attachment a try, but you’ll need to unlock it first. Let’s go over all of the challenges available this week and how to complete them as quickly as possible.
