A few questions

So here are my questions:

Number 1: will the Reach armor start showing again seeing as it’s coming to PC

Number 2: My Halo 4 Campaign (original Xbox 360 version second hand from EB games) it says "Players failed to load a player may be missing DLC, I am the only person in the lobby it has worked just fine but it randomly does this,

Any help would be great thanks and also answers for reach armor.

See this for the latest update on the progression system for Reach.
From a Reddit AMA:

> “Q. Seeing that a Xbox Live account will be required, will progress / multiplayer progression carry over from console to PC (ie: Halo Reach multiplayer ranks and unlocked armors)?
> A. Within MCC, yes, your progress and progression will carry-over between the console and PC versions. All stats, achievements, Forged maps, and game variants will be shared between all of the games within MCC. Mid mission saves will be unique to each platform and cannot be shared.
> Your Halo: Reach unlocks and progression from the original game on Xbox 360 will NOT carry over to MCC.”

As for the Halo 4 problem, here’s a thread that might help.

The halo reach armor will come to halo reach on the mcc
