Anything?Posted by planting42 on 30 Dec 18 at 23:32 I'm playing thru the "Master Chief Playlist" MCC, with 46 missions. After finishing "Sierra 117" mission, I did not get the Landfall achievement. I was able to continue forward with the playlist. I _did_ get achievements for other Halo 3 missions. I'm on XBox. Happened May 2023.Posted by noleander on 03 Jun 23 at 20:52 No unlock for me in June 2023. I unlocked both skulls and all 3 caveman achievements in the same run, no skulls active, but did not get completion credit after boarding the pelican. The level does show as completed normal solo on the mission select screen.Posted by DiaI Square on 24 Jun 23 at 23:10 I have same problem as above 5/28/24... playing on steamEdit: played the mission a 3rd time this time in a playlist and got par-time at same time everything poppedPosted by TheOneBlackRose on 28 May 24 at 19:00 Finished the level twice now. One from rally point Charlie and once from the start, still won’t unlock, even with no skulls active. Very frustrating.Posted by Derek1337 on 22 Dec 24 at 17:38 ^ All the achievements are delayed in this game as of recently.I've had no issues with them unlocking, but 99% of the achievements so far have popped late.I did the Ark in Halo 3, got all the skulls and terminals, and didn't go in a vehicle on Legendary.Skulls & terminal achievements popped 30 minutes after I was done, and the no vehicle one popped 8 hours later in the middle of the night, saw it when I woke up.Annoying, but at least they're popping. Even in your situation, I see that your achievement popped 5 hours before you wrote this comment lol so it might've done so silently.Posted by v Xndr v on 28 Dec 24 at 00:27 Leave a comment
