So I’ve had the game for quite sometime just never played and got into it and realized how much I’ve missed out but here is my point. So there is an armor set for watching the nightfall series(didn’t realize it costed $15 xD) and there is the MarkVI Gen1 armor set I believe which I got, it comes in scarred or just regular versions, but is there anymore armor sets that I could get that cannot be found in req packs? Thanks in advance 
plus sorry for long description not good at writing forum posts if that makes sense lol
The armor you get from watching Nightfall, and Mark VI gen1 regular and scarred can all be found in req packs, actually. Off the top of my head, armors that you can get but aren’t found in normal packs would be Achilles, Athlon Champion (maybe…not sure if that HCS pack is still available), the Timmy and Olive helmets, and all of the helmets found in the Classic Helmets special req pack.
Timmy helmet - can be achieved by playing custom games for alot of hours.
Helioskrill armor - complete every Campaign mission in the MCC on Legendary.
Olive helmet - forge a map that appears in multiplayer.
Achilles armor - grind commendations with a Spartan Company.
All other armor peices are no longer unlockable that I know of.

Helioskrill is also available from normal req packs
