How do you pass halo3

Because of the vagueness of the question, it makes it increasingly difficult to find the requested response. If one means, "How do you pass the Halo 3 campaign?" then it can be achieved by slowly working your way through each individual level, until the accomplishment has been achieved. Halo 3, as did the previous titles offers a variety of difficulties for the game to be beat on. For new comers, Easy or Normal should be played first, until the have a better understanding of the game. For more experienced players, Heroic or Legendary can test your skills. And for the few prestigious veterans who demand more, Mythic Difficulty will put a strain on even the most weathered players. Mythic Difficulty is begun by activating all the hidden skulls found throughout the game. Few would be able to make it past the first levels in this difficulty, as the HUD is gone and opponents are in their highest ranking forms, along with many other interesting tweaks. Either way, time must be devoted in order to "pass halo 3" and offers a mysterious ending if beaten on Legendary.
