It was a pretty huge letdown after I completed the game on Legendary with All Skulls On (LASO) and got absolutely nothing. There should be a notable reward for beating the game on Legendary and then an even more substantial reward for LASO completion. Alas, there is nothing. Seems silly to me that there wouldn’t be.
If it was a really good reward, it might encourage players to buy the campaign or to play it if they have Game Pass. Currently the Campaign is largely underplayed (less than 10% have even completed the main Campaign as of writing) so this may be a solid incentive to get people in.
“This is the new model”.
At least that is what the CM said 
I keep hearing that. Kinda frustrating that “the new model” keeps being the excuse devs are using to put out lower quality content at disproportionate prices.
I liked the nameplates in MCC for beating Legendary in under 3 hours.
LASO had nameplates too but nothing else. Just the achievement.
MCC is kinda different though. It’s just a collection of already complete games that had their own progressions and sets of completion rewards individually.
This is true and it explains why gaming today MP games have gone to crap.
Part of me hopes that the unlocks are broken. There are 3 items in the armory that are locked to the campaign but as far I’m aware, No one has unlocked them.
Should be two legendary stances and a weapon charm
I totally agree. I love the idea of getting more from campaign - I personally think we should get Chief’s exact campaign armor, visor, and coating for our multiplayer Spartan after beating the campaign on legendary, and some cool campaign-themed armor effects and other flashier cosmetics would be good too. I think certain previous games did something like this, though I could be wrong. I also just think we should have weekly campaign challenges in Infinite like we do in MCC. Simple stuff, like ‘kill 75 enemies with CQC weapons’ or something like that. We’re paying $60 for just a campaign, the least they could do is give us some flashy cosmetics to earn and more ways to earn XP that aren’t related to playing MP (most of the ones we find in the campaign are good imo, I just want more of them). Giving us ways to earn MP XP in campaign would also incentivize more players to buy and try out the campaign.
