A pair of new melee weapons are coming to Call of Duty: Black Ops Cold War and Warzone, according to data miners: a baseball bat and the ballistic knife.
"Some of its Camo Challenges include kills, backstabber kills, executions, enemies while injured, enemies while sliding, smoke/stun/flash kills & multi-kills!" Zesty wrote on Twitter.
A second data miner, Nanikos, found similar files referring to the ballistic knife. Its challenges include getting Longshot medals, getting short killstreaks, destroying equipment, and more. These challenges appear similar to those applied to a recently added crossbow.
There's no guarantee these weapons will make it to Call of Duty, but if they do come, they'll probably arrive in Call of Duty: Black Ops Cold War Season 3.
