So it turns out after doing the Experience Halo 5 I had a download waiting today called “MARCOM” which is the promotional REQ Pack with it’s size as 9.51MB and the description being: Promotional REQ packs often contain a pre-determined reward along with a limited amount of randomized content
Wonder why it’s called MARCOM though.
Thinking it over. MARCOM is likely the name of the system / program that distributes all the Promotional REQ’s to people and is an add-on to enable that person to get them
MARCOM, which is an abbreviation for Marketing Communications, is the placeholder download for any and all promotional packs you receive, unless they are specific promo packs outside of things like McFarlane, Megablocks, Halo 5 Experience videos and etc.
