🔨 Wielding Your Reward: The Sledgehammer
Unlocking the Sledgehammer feels like finally getting the master key to a vault of pure destruction. Its impact is less a hit and more like a localized earthquake – enemies crumple before it like sandcastles under a wave. While it swings with the deliberate pace of a glacier calving, the payoff is immense. Remember:
-
One-Hit Wonder: In core MP and against most unarmored Warzone foes, it's a guaranteed down.
-
MWZ Power: It shreds low-tier zombies and is surprisingly effective against Mercs with the right perks.
-
Trade-off: Speed is its weakness. Miss, and you're vulnerable. Pair it with a fast secondary or a throwing knife for quick follow-ups.
This week's challenges are a golden opportunity, smoother than polished obsidian. Focus on the modes you enjoy most, leverage the tips above, and that Sledgehammer will be yours in no time. Get out there and start smashing! 🎮💥
