The Halo 4 Forerunner displays how it has evolved through the entire series.
The Halo 4 Forerunner gives the game a new look with the new enemy “Promethean” and all the other knights and how they evolved during the production. The prometheans are made from the knight, crawlers and knight watcher which make them more powerful and to intimidating that any other enemy that there has been. Along with all the trial and errors that they did until they had it right. Now they moved into the compilation of the weapons, like the shotgun, riffle and main weapons. Details were done to the customization of the weapons to have more than just a weapon but also a piece of weapon that feels right. It was said also in the video that Halo 4 is the sequel of Halo 3 and that when they were making it they realize with all the feedback from the community and what changes were being made at the game was in production.
