With Halo 3 is the story of the super soldier Master Chief, of the hostile alien race fighting against Covenant and earth, free from the threat had ultimately come to a dignified end. But the Halo universe offered much more flexibility and fast it was clear that Bungie still wanted to develop another Halo game. This should be the basic requirements for the title of autonomy and a gloomy atmosphere. In Halo: Reach is therefore not Halo 4 but a completely independent project. Reach will also not be the new beginning of another series but remain closed in themselves. Chronologically, the game settled before Halo 1, becoming the prequel of the series. One remains the same: Halo: Reach is like the first three parts of an action-packed first-person shooter. The genre changes not Bungie also.
