A new feature that appears to have been added into Call of Duty: Warzone without being mentioned in the patch notes: the ability to drop weapons.
Since Warzone’s launch in March, players were not able to drop a weapon in Warzone if they picked it up. Players could only replace a weapon with another weapon.
Now, with the new update, players can drop a weapon that they picked up and ping it for teammates to get.
A video posted to Reddit shows the ability to drop weapons on PC has been added to the Inventory/Drop menu, allowing players to drop their currently equipped weapon.
This could be especially useful in situations where a teammate comes back from Gulag/bought back and have no weapons, and now can take one from a teammate.
