Weapons in Call of Duty: Black Ops Cold War generally require you to break your back in multiplayer to unlock them. You will need to complete difficult challenges to unlock weapons from previous seasons, or to get new weapons that developer Treyarch adds mid-season.

Fortunately, for those who prefer Zombies over traditional PvP multiplayer, all of these weapons now have their own separate unlock challenges specifically for Zombies mode. After unlocking these weapons, you can use them for Zombies, multiplayer, or Warzone.
