How to unlock the Sledgehammer in Call of Duty Cold War and Warzone
Thanks toModernWarzone capturing a screenshot, we know what you’ll need to do to unlock the Sledgehammer in Cold War and Warzone. It’s pretty tough, but get on a small map in Cold War multiplayer and you shouldn’t be in too bad a place. Anyway,here’s how to unlock the Sledgehammer:
Using the Combat Knife, kill 2 or more players rapidly in 15 different matches.
These 15 matches can be in Warzone or Cold War Multiplayer, and progression will stack across the two, but remember - it’s a whole lot easier to pull it off in Cold War. Smaller maps, multiple lives, and less armour all mean you’ll be able to pull this off faster outside the confines of Warzone.
Best class for quickly unlocking the Sledgehammer
Of course, if Perk Greed isn’t your cup of tea, Danger Close is a solid alternative. You won’t have all the perks you want, but the ability to spam Flashbangs or Stun Grenades with Quartermaster means you can disorient enemies and shank them all over the map.
That’s all for our guide on how to unlock the Sledgehammer in Warzone and Cold War! There’s plenty more guides here on RPS if you want them though, including some gun guides, like thebest XM4 loadout for Cold Warand all theweapon stats for the Cold War guns.
