With the Season 4 Reloaded update, Call of Duty: Modern Warfare 3 received new weekly challenges across Multiplayer, Zombies, and Warzone. The current season features eight week-long missions that you can complete for rewards.
NEW CONQUEST EVENT CHALLENGES & REWARDS! (Free Mastery Blueprint & MORE!) – Modern Warfare
The rewards include custom aftermarket parts, blueprints, and camos for your weapons, and you can also earn some XP as a bonus. Below I've listed the current weekly challenges available in MW3.
Note: The recommended weapons mentioned in the challenges will be highlighted in the crafting menu.
Complete five weekly challenges from the list above, whether it’s for Multiplayer, Zombies, or Warzone, and you’ll unlock Week 5’s reward: the Sledgehammer Melee. Give it a try if you’ve been wanting to run through the maps with a new Melee weapon in MW3 Multiplayer. Like any other weapon in its class, it can kill enemy players in one hit. Keep in mind that, since the Sledgehammer is a heavier weapon, it swings slower and feels sluggish compared to a Combat Knife or Karambit, so make sure to time your strikes correctly so you don’t miss.
