In halo ce:The Wraith that flips (with the inactive and unarmed brute on top of it lol ) is a problem carried over from the pc version if i am correct even the classic xbox version wich basicly means its a classic (jk) but would be nice to have that fixed.
Flood carrier forms no longer turn the targeting reticule red
Spirit drop ships no longer fire from their turret, the shots come form another location
In the final mission when you fly to the control room the last two wraiths that spawn: The one on the right flips over.
It wasn't in the xbox version.
Also in halo 2:
Grunt birthday party skull does not function properly. It functions like it's halo 3 counterpart. The halo 2 Grunt Birthday Party Skull is supposed to turn head shots into plasma grenade explosions. If necessary you guys can add a "Classic Grunt Birthday Party Skull" that has the original halo 2 Grunt Birthday Party Skull effect.
Halo 3: The second skull in the level Cortana spawns and rolls off the ledge into an unreachable pit. That needs to be fixed too.
Halo ce: Doesn't have the original heads up display or sound effects.
General update feedback: Hello 343 I personally request that for the next update you guys really really focus in on the campaigns. They have actually degraded a little during your blitz of new MCC updates. I understand focusing on improving the MP side of halo and adding new features, but I really feel that for at least one update the campaigns need to feel the love. Please fix bugs that appeared in the PC releases, Please fix the bugs that are new to the MCC. Thanks for all the hard work you guys have put into improving the MCC! I really respect it. I will actually state here that I will purchase a copy of halo infinite when it releases because my trust in your company has been restored.
