Armor Unlock

Ok how do I get the CQB and MP helmet for reach i know it’s kinda old but eh i thought I’d play again.

for each piece you need to unlock specific achievements in Halo 3, ODST and Reach, as well as hitting certain carrer milestones in the Halo Waypoint app on Xbox 360. Go into your Halo Reach career stats in the Xbox 360 app and it will give you more specific details on what you need to do.

Ok Phil . Thanks for the info
