Forum:How do get the halo normal campaign achievement

I've finihsed all the missions on normal difficulty, and i've unlocked all the achievements as for completing all the missions on normal difficulty. But for some reason, I haven't managed to unlock the 'campaign complete: normal achievement'. keep in mind that I did not necessarily do all the missions in order (i'd sometimes replay a level before moving onto the next one), but that is no reason for this to happen, right?

any advice on how i can get the achievement

you watched the first video on normal right? (the arbiter on halo 2) make sure you watch that first video and don't skip it and hit a after you go to the credits if it doesn't work just wait you will get it.

if you tried that tell me what game this is. if you didn't beat the campaign in one blow make sure it's normal when you return. you can't skip checkpoints (lets start at checkpoint alpha!). it should work but if it doesn't idk.
