So I’ve gone through the legacy achievement lists and found that there are quite a lot of achievements that didn’t make it into the MCC from their 360/ GFWL counterpart. for some of these achievements, I cannot understand why they never made their way onto the MCC from their respective games.
There are even more multiplayer achievements for DLC-specific maps, I didn’t include them because well… MCC no longer has VETO so if for some reason a dev saw this list and thought it would be a good idea for them to add them back to their games, I imagine it would be insanely tedious getting them ones. I remember having to boost the Reach dlc achievements because when 343 took over they removed the DLC playlists… ahh… what a different era in video gaming when the population was split over DLC maps.
Here is the list:
