38 2 4Actions Report Solution I think the easiest Halo 2 playlist is "Boss Fights." Complete The Oracle, Regret, and The great Journey on Normal. They're all pretty easy levels.Showing all 4 comments. Leave a comment. Did two different playlist and No achievement. It show 0/4 for fan favourites and 0/3 boss fights. DONT WASTE YOUR TIME WITH THIS!!!Posted by Soldierkimi on 08 Apr 21 at 12:48 Worked for me today, did the boss fights playlist and the achievement unlocked as expected.Posted by Lonewulfeus on 09 Apr 21 at 19:37 Something which is quite strange, I was doing this co op and it wouldn’t register as completed for me but it did for my friend who was the lobby leader, May be worth considering when doing this achievementPosted by BeardyBrady on 19 May 21 at 08:33 I didn’t get it in co-op eitherPosted by LuckySean2 on 18 Aug 23 at 04:12 Leave a comment
