The mid-season update for Season 4 is now available in Call of Duty: Modern Warfare 3, bringing with it a new set of Weekly Challenges. Completing any five of these challenges will unlock a new weapon or powerful Aftermarket Part. This week, completing five challenges will unlock the Sledgehammer melee weapon, capable of killing most enemies in a single hit.
This week's challenges are also quite easy to complete, making this the perfect time to jump in and unlock some new items. This guide will briefly go over how to unlock the Sledgehammer, and we'll cover how to complete every Week 5 challenge in MW3's fourth season.
Week 5 Challenge Reward
If you complete any five challenges this week, you'll unlock the Sledgehammer melee weapon for use in Multiplayer, MWZ, and Warzone. The Sledgehammer trades attack speed for raw damage, one-tapping almost everything you swing at. Once this season ends, you can obtain the Sledgehammer through the Armory Unlocks system.
