A few days ago i passed Halo:CE, Halo 2, Halo 3 and Halo 4 on legendary in Halo MCC and i unlocked the achievement but I haven’t unlocked the Helioskrill armor set in Halo 5. I’ve been checking daily and it’s still not there. Can anyone help?
Yeah it’s been doing this for a while. Just wait it out.
Also hate to break it to you, but people can get this armour from a random card pack now, while you and me grinded all the Halo’s on legendary, this is a sad world 343 had made for us.
It looks like you did not complete all of the missions. All of the missions need to be completed before you can unlock the armor. I checked your record here on mcc, it looks like you finished some missions in coop but not all of them.

This. You need to make sure the missions have registered as completed on Waypoint, or else it doesn’t give you credit for completing all campaigns on Legendary.
you need to beat the following Halo ce coop truth and rec, Keys, the Maw
Halo 2 solo arbiter and Oracle
halo 3 solo Sierra 117 Crows nest The Storm The Arc
halo 4 either coop: Dawn Requiem Forerunner Shutdown or solo infinity reclaimer compser midnight
ive noticed you can mix and match coop and solo for the games, but you need to do them fully one or the other.
also you need to make sure it registers on waypoint here to get it.
Oh okay. Thanks for your help 
The armor automatically unlocked for me. So maybe it just took some time to update
Congratz with the armor, wear it with pride! Feels good to have finished all those campaigns on Legendary, right?

That really grinds my gears. Some work for it and others get lucky. Talk about fair.

I’m waiting for it as well just finished the campaigns. How long did it take to show up, May I ask?
Lol, I just unlocked it a few days ago from a gold pack

Can you be done with the parading around because you got lucky? I have seen you on another helioskrill related discussion. Please stop.
I didn’t realise there were any armours in H5 (other than Achilles) that you could get any way other than random req packs. Is Helioskrill the only achievement armour? Am I right to gather I can just (‘just’) complete every Halo CE - 4 mission on legendary to unlock it?
The mark 6 helmet and broken version are some of the only other achievement based armors asides from helioskrill.
