So I been playing the campaign and I’m really disappointed with halo.
I’m huge fan of halo that’s the only reason why I bought Xbox, and I found a lot of problems.

  1. [Halo]My achievements don’t unlock .
  2. [Halo 2]My missions won’t load and some take 30 min. To load
  3. [Halo 2] The game crashes if there is too much action.

And some other small stuff.
I wish I never bought this game , really disappointed.

i don’t have any problems. it may be your internet. i did miss one achievement due to my internet but i got it later when my internet got back up.
