I have this code

wait(2)
local Players = game.Players
local ReplicatedStorage = game.ReplicatedStorage
local ServerStorage = game.ServerStorage
local ChangeGUITextEvent = ReplicatedStorage.ChangeGUIText
local Maps = {workspace.MapTeleports.Map1, workspace.MapTeleports.Map2}
local DealDamage = ReplicatedStorage["5&mw5EE'5jnKxmw3"]
local playersLeft = ReplicatedStorage.PLFT
local LastMap = workspace.MapTeleports.Map1
local HasWon = false
function TeleportPlayer(player, Character, SpawnPoints)
	local SpotsToSpawnIn = {}
	local TheirSpot
	for i, v in pairs(SpawnPoints:GetChildren()) do
		table.insert(SpotsToSpawnIn, v)
	end
	for i, v in pairs(SpotsToSpawnIn) do
		TheirSpot = SpotsToSpawnIn[math.random(1, #SpotsToSpawnIn)]
	end
	Character.HumanoidRootPart.CFrame = TheirSpot.CFrame
end

function WhileTrueLoop(player)
	spawn(function()
		while true do
			repeat wait() until #Players:GetPlayers() >= 2
			wait(2)
			ChangeGUITextEvent:FireAllClients("intermisson")
			wait(5)
			ChangeGUITextEvent:FireAllClients("")
			for _, vPlayer in pairs(game.Players:GetPlayers()) do
				if vPlayer then
					vPlayer.KillsThatRound.Value = 0
				end
			end
			for _,v in pairs(workspace:GetChildren())do
				if v.Name == "Handle"then
					v:Destroy()
				end
			end
			wait(5)
			local Character = player.Character or player.CharacterAdded:Wait()
			local ChosenMap
			if LastMap == workspace.MapTeleports.Map1 then
				ChosenMap = workspace.MapTeleports.Map2
			elseif LastMap == workspace.MapTeleports.Map2 then
				ChosenMap = workspace.MapTeleports.Map1
			end
			TeleportPlayer(player, Character, ChosenMap)
			local UnclonedPlayersKnife = ServerStorage.Knifes:FindFirstChild(player.OtherValues.CurrentKnife.Value)
			if UnclonedPlayersKnife ~= nil then
				local PlayersKnife = UnclonedPlayersKnife:Clone()
				PlayersKnife.Parent = player.Backpack
			else
				local PlayersKnife = ServerStorage.Knifes:FindFirstChild("ClassicKnife"):Clone()
				PlayersKnife.Parent = player.Backpack
			end
			ChangeGUITextEvent:FireAllClients("The map chosen was " .. ChosenMap.Name .. ".")
			playersLeft.Value = #Players:GetPlayers() --resets this value
			DealDamage.OnServerEvent:Connect(function(MyPlayer, HitPlayer)
				playersLeft.Value = playersLeft.Value - 1
				if playersLeft.Value == 1 then
					HasWon = true
					ChangeGUITextEvent:FireAllClients(MyPlayer.Name .. " has won!")
				end
			end)
			if HasWon then
				break
			end
			wait(5)
			ChangeGUITextEvent:FireAllClients("")
			wait(95)
		end
	end)
end

Players.PlayerAdded:Connect(function(player)
	wait(3)
	WhileTrueLoop(player)
	spawn(function()
		while wait() do
			if HasWon == true then
				HasWon = false
				for _, v in pairs(game.Players:GetPlayers()) do
					local vCharacter = v.Character
					vCharacter.Humanoid.Health = 0
					wait(3)
					WhileTrueLoop(v)
				end
			end
		end
	end)
end)

but it will only teleport the player who won (sorry for code bomb)
