Note: This list does not include 'hard to get' achievements like the DLC map specific achievements for Halo 3, 4, and Reach. I don't expect them to fix the Halo 2 PC achievements but a discussion about the remaining achievements would be nice.Ĭurrently there is 29 unobtainable achievements worth 415 gamerscore. I don't know if there is an easy solution for this as they could provide a patch that just nulls the requirements or maybe even make it so people can run private servers again. Halo 2 PC on the other hand has unobtainable achievements due to the servers closing. A patch they have yet to receive since launching the games. It includes every variants of the games from Spartan Strike on iOS devices to the Chinese variant of the Master Chief Collection.ģ of the 4 games being listed here would just require a patch, probably. It's misleading how 343 feels about this since they do promote a "Halo Score" on their website which collects your gamerscore from all of their games (with Halo 2 PC being the only exception).

On TrueAchievements alone, there are many people that nearly have every achievement for the series but are missing the ones listed below. I feel there's more in the Halo Waypoint, XboxAchievements, and TrueAchievements community but maybe this can help shed some light on the situation. I know there's only a small niche of people in this subreddit who would like get every Halo achievement. Somebody brought this up the other day so I thought I'd do some additional research and provide a definitive list.
