no helioskrill? help

i just finished the halo master chief Collection on legendary, i have completed halo 1 CE, halo 2, halo 3 and halo 4. all missions say completed on legendary, still i have not unlocked anything in halo 5 customization. am i not supposed to unlock helioskrill? or do i have to Complete ODST as well?

also what is the surprise they mention in the Message of the day happy newyear?

Make sure all your achievements unlocked, most importantly the “Legend” and “Legend of 117” Achievements. (You do NOT need to beat ODST)

Also give it time to recognize. I was lucky, switched to halo 5 right after finishing H4 and it was there.

*** it will not appear all the way to the right like most new armor sets do, instead it will be at the very beginning (far left)

Ps. The surprise refers to things they have planned for throughout the year.
