How to Unlock Katana in Call of Duty: Vanguard and Warzone

There is not a single beautiful but elegant and deadly melee weapon in this world. Katana has found her way in Call of Duty: Vanguard and Battlefield in part one.
The Katana is a Japanese single-edged sword that can be deadly in close combat. You’ll cut and dash through your enemies like a pro CDL through enemies in instant public battles with this melee weapon.

Katana is unlocked through an in-game challenge. The challenge is as follows:
- Get five kills with a melee weapon in a 15x match.
Equip a combat knife, Sawtooth, or Combat Shield and begin melee combat with your opponents at reckless abandon. You need to get five kills per match and then finish the match to get credit for the challenge. Don’t back down after reaching the kill count or it won’t count towards the 15 required.
Challenges can be taken in Battlefield, but it’s easier to do in Vanguard Multiplayer.

Alternatively, you can unlock instant access to Katana by purchasing the Moon Forged pack from the in-game store. This bundle costs 1,500 CoD Points and includes access to Katana, control skins for Shigenori, an ending move, an MVP highlight, a calling card, an icon, a gesture, and a turn skip the battle pass step.
