What are the ways to remove all the zombies from the map after the wave ends, and sometimes I run out of zombies and some of them remain on the map. They are cloned to the game.Workspace
Using this is not recommended at all. As it can lag out your pc. I recommend doing something like what BestCreativeBoy commented. If you want, you could use this
for i,v in pairs(game.Workspace:GetChildren()) do if v.Name == "Drooling Zombie" then local humanoid = v:FindFirstChild("Humanoid") if humanoid then v:Remove() end end end
