Would I need to add a spawn for this script?

wait(6)

while true do
	p = game.Players:GetChildren()
	randplayer = p[math.random(#p)]
	randplayer.TeamColor = BrickColor.new("Camo")
	randplayer.Character:BreakJoints() 
	m = Instance.new("Message")
	m.Parent = workspace
	m.Text = randplayer.Name.." is the zombie! "
	wait(3)
	m.Parent = nil
	wait(300)
	for i = 1,#p do
		if p[i].TeamColor == BrickColor.new("Camo") then
			p[i].TeamColor = BrickColor.new("White")
		end
	end
	m.Parent = workspace
	m.Text = "End of game"
	wait(4)
	m.Parent = nil
end
