Halo 3-Complete
Halo Wars-Complete
Halo 3: ODST-Complete
Halo: Reach-Complete
Halo: CEA-Complete
Halo 4-Complete
On Xbox One:
Halo: Spartan Assault 27/30
Congratulations, man.
Now to move onto Halo: The Master Chief Collection 
Nice! Last 2 halos I need to finish are ODST and Halo wars.
Congrats
Congratulations, I’m just missing that General achievement in Halo: Wars.
nice i’m still working on my games, for some reason my halo reach and halo 2 don’t show up for me playing them?
congratulations to me is one of my goals to get all the achievements before leaving collection of Master Chief
I still got a bunch of Reach DLC ones to get, and HSA.
That’s awesome! I wish I had a lot of time to complete it like you have. But oh well, at least you got something, I’ll congratulate you on it. 
@BATMAN TST
Well done! You’re ready for The Master Chief Collection.
The only Halo I need to complete now is Halo Wars (damn ranks achievements and DLC I will start after the first 1000G) and Spartan Assault on some platforms.
@KSI NEEDLEMOUTH
Maybe you changed your Gamertag after the last time you played Reach ? If so, you need to complete at least a game while connected to Xbox Live to update all your stats.
For Halo 2, if you’re talking about the Xbox version then it’s the same problem. If you changed your Gamertag after the servers closure, you won’t be able to retrieve your stats. The stats of Halo 2 scans the name of the account and not the account himself. If you’re talking about the Vista version, no stats are tracked from it but I don’t know about achievements (Our Halo Gamerscore on profile page).
