i just finished campaign whilst my internet was down so i got none of the acheivements even though whemn i go on the levels they all say solo completed. i spent over 13 hours doing it to get the mark 6 things. so annoyed and will not be doing it again for sure. will 343 update this to sync this problem? i hope they do because many others ahve had the same problem and it makes me want to quit playing if im honest.
thanks
You must have obtained the achievement even if played offline.
To get the armor you have to have played it online.
Also, there is a lot of speedrun videos you can use in Youtube to make it much faster. You can even complete Shutdown in 5 minutes.
Have you checked your commendations? Hopefully, it will show you which level you missed.
You have to complete the Campaign Commendations to get the Mark VI armour. You have to be playing online to get Commendations.
If you already beat the levels then you can load the last checkpoint to get the commendations. It makes the process much faster if you decide to go for it again.
the load last checkpoint thing wont work. youll have to do it all over again. that happened to me the day it came out, and my internet went down. and really, 13 hours? halo 4s campaign was the easiest out of all of them. it took me 7 and a half. just do it again.
