New to Halo 5, Questions about Req Packs

So I just bought and installed Halo 5 and received 3 req packs. So I was wondering if there was anymore.
Got online and saw some options for promotional stuff and how to get some more.

  1. Watch the 5 Nightfall videos.
  • I have the Halo: Nightfall installed and I am not allowed to watch them for some reason. Are they any closer to fixing this problem?
  1. Halo 5: Guardians Experience (View the 10 Short films)
    - Went to the link “http://experience-halo-5-guardians.xbox.com/” and the link is no longer active. Any chance this will be opened up again?
