The best Ninja Turtle’s weapons of choice are now available to use in Call of Duty: Warzone and Black Ops Cold War.

Raphael, the red turtle, loves his sais. You, too, can dual wield these daggers like a ninja yourself as you run around multiplayer, Zombies, or Verdansk. But they’re only available to unlock during the two-week “The Numbers” event in both games.

Several trucks have been placed throughout Warzone in Verdansk by Perseus, who’s using them to spread the number broadcast and activate sleeper agents. All you have to do, though, is walk up to them and interact with them to hear the number broadcast and finish a challenge.

In Black Ops Cold War, there’s a bit more work to be done, with several challenges taking place in either multiplayer matches or Zombies mode. Whichever game you choose to play to unlock the Sais, the weapon can be yours pretty quickly.

Here’s how to unlock the melee weapon in both games.
