WC: Halo is the most successful Xbox exclusive in the consoles history. Original developer Bungie created a first person shooter masterpiece back in 2001 and even though they have since left the franchise, Halo 4 has proved the series is more than safe in the hands of new developer 343 Industries. While Call of Duty remains the most popular first person shooter, Halo is widely regarded as the best. Some prefer the manic pace of Call of Duty while others love Halo’s more skilful approach. Whatever your preference, the one area where Halo trounces Call of Duty is perhaps, the most important when it comes to online warfare. Maps define an online experience and Halo has a rich and varied selection that is miles ahead of the competition.
