The Achievments are broken up into sections. First will be Overall Achievments. These aren’t specific to any of the games and can be earned throughout the games. In certain ones, they have to be earn for each game. For instance playing each campaign 1-4 on Legendary.

After that list are lists respective to each game, Halo: CE, Halo 2, Halo 3, Halo4.

There are some returning achievements with lots of new ones as well. There is a heavy emphasis on campaign achievements. This makes sense as it’s the story of Master Chief so far in the four games. I LOVE it! Some are quite clever…

So let’s get started first with the Overall Achievements.
