This is just for those who are struggling with completing the game & getting frustrated.
I just completed it 100% all achievements with a total playtime of just a little over 4 days.
That includes playing warzone for fun & helping out a few people, actual time on achievements is around 1 1/2 days.
SO I CAN BE DONE GUYS 
don’t stress it.
I only had a few issues with achievements not unlocking correctly (i.e. Warlord & 3 campaign ones) but a system reset & profile redownload fixed those 
so they are all obtainable! … With a little patience, luck, cursing, yelling, a big bottle of Rum, a pack of Marlboro & some pizza rolls 
.
So good luck guys & don’t give up!
Hey, well done. It’s a PITA that you have to jump through hoops to unlock some of them though…

Yeah it got very annoying at times, like posting in the club or in forums for a partner to help with this achievement or that achievement only to get 3 people & discover 2 of them are 8yrs old that just got the game & haven’t played it for more than 1hr 
. Or do it like 4 times because it didn’t unlock only to find out it unlocked online the first time but your Xbox just doesn’t know it
I’ll tell you what though if they add speedrun achievements to this thing I’ll have them nailed quick!!
How did you get the one where you have to assassinate an Elite at the same time? That is probably the more difficult one I have yet to get due to the AI being unpredictable

Co-op with 1 other person & a mic
I’m working on it, most of mine I have left are the heroic difficulty specific ones which make you do some weird thing to get it. I’ll get there. Eventually.-

I go through phases of wanting 100% achievements unlocked. I will probably unlock all the achievements this coming winter but still have about 50% left to go.
Congratulations for 100%, I also made all the achievement 
Yeah it is fun getting them all done. I’ve been struggling with getting all the Medals. There are a few I’m just not good enough to get.
Yea the achievements for halo 5 aren’t that tough except for the annoying AI related achievements. Killing warden at the same time, charging up the hill with that elite, because I did it solo.

Yeah that was tough doing solo. Trying to keep him from running too far ahead and getting killed.
Congrats, I would have 100% it, but unfortunately I hardly got any friends to do co-op achievements with :’(
I do have one friend I could do it with but my good net is down to attempt these achievements.

That Elite achievement was a pain. My friends and I had a difficult enough time getting it done on co-op.
