Already partially exists iif we look at that WIW tag that spawns weapons in certain locations but nobody ever uses it.
Can be altered by another tag to drop the weapon in the location of the player instead, but i ask;
Why? You already have ammo drop on death, and why would you need someone elses weapons if the weapons you just used are the ones u chose in the gameroom you probably wouldnt want to switch them out right unless youre a level 1 scrub and kill a full donor player
