Si usted necesita la mayor cantidad de flexibilidad cuando integre Unity Multiplayer Services, usted puede utilizar la clase NetworkTransport directamente. Este método requiere más código, pero le permite a usted controlar cada detalle de cómo su juego se integra con los Multiplayer Services.
Este es un ejemplo de cómo conectarse directamente utilizando la clase NetworkTransport:
using UnityEngine;
using UnityEngine.Networking;
using UnityEngine.Networking.Types;
using UnityEngine.Networking.Match;
using System.Collections.Generic;

int m_HostId = -1;
// On the server there will be multiple connections, on the client this will only contain one ID
