local tool2 = "Darkster Liquid"
local tool3 = "Forgerler Liquid"
while true do
wait()
game.Players.PlayerAdded:Connect(function(Player)
	Player.CharacterAdded:Connect(function(Character)
		if Player.Backpack:FindFirstChild(tool1) and Player.Backpack:FindFirstChild(tool2) and Player.Backpack:FindFirstChild(tool3) then
			game.Workspace.ZombieLiquidNonFixed.Transparency = 0
		else
			print("Player does not have tool in backpack!")
			end
		end)
	end)
end
