Halo achievements

Does anybody happen to have a list of achievements that can be unlocked in custom games, just so I can clear them up? Thanks

There really isn’t a list of custom game related achievements, but if you look at the full list of achievements, you’ll see that there are many that can be achieved in custom games. The H2A Achievements can be done, but the ones that say “matchmade games” can not be done, I believe.
