Halo 3 Limited Edition

Hey everybody, I'd like to tell y'all about Halo 3 Limited Edition. In case you don't know what it is, it is Halo 3 with an extra disc, a book explaining about the covenant, and a user manual with a different cover (I think). The story of how I got this Halo 3: Limited Edition. I went to Gamestop in the St.Louis Galleria and bought the regular version of Halo 3 for about $20. It didn't work, so that evening I went back and exchanged it, but the guy at the counter gave me a limited edition of Halo 3, saying that it had some bonuses. It turned out to work fully, and it had many more features. I gladly took it and I guess that was all the store had, that they were sure worked perfectly. Needless to say, thanks random guy at the desk. Today, I felt like I should write this because I beat the campaign on normal, right before I went to church. I have watched many YouTube videos about it, and it didn't seem very hard to do as they said. If you look at my gamertag and service record, you will see that I just got EVA armor. I am also waiting for getting the Hayabusa Armor since I know how to get all the skulls. IWHBYD still didn't work for me today however. Nevertheless, I will triumph someday! I think I am more likely to get Recon Armor before Hayabusa or any of the other armors.
Here is a video that demonstrates how easy the level is
