Some of these I have seen others report and some I haven’t. Please read 343i and please fix.
UI: Not registering any of the skulls I have collected in stats even though all on Halo CEA collected and others collected in Halo 2A and Halo 3.However it registers the terminals I have unlocked. All in Halo CEA and around half in Halo 2A.
Halo CEA: Achievement previously stating done unlocking but has not unlocked later like other achievements. Specifics Halo level completed various times and dates, achievement not registering, or avatar unlocked in customisation. Also walk it off achievement completed about 9pm BST time not registering.
Co-op play very latent connection, both players open nat, very good connections.
Hit detection Headshots and shots generally not detected against ai. Mentioned this will be fixed but lives I lost playing solo on Legendary and also on co-op probably will not be wiped from my stats.
Skulls unlocked cannot be selected, Not sure if this is an error or intentional as I know some of these were offered as pre-order bonuses, eg. Boom and Bandana. An in-game message confirming that they are not able to be used until 12/12/14 would be nice as I assume this why we cannot use these.
Halo 2A
Whilst chasing Phantom on Arbiter level in the Banshee music cuts out, this has happened every time I have played this level at this checkpoint.
Whilst using scarab skull columns cannot be shot on Sacred icon on Legendary, therefore you cannot get out of the first room play this level while this skull is enabled. Also opening cutscene on this level is glitchy.
Halo 3
Achievements completed after 9pm BST time not registering, 4 player co-op Legendary Co-op.Tsavo Highway, The Storm, All skulls found, and both levels completed successfully, nothing. Also Tsavo Highway after leaving garage with warthogs, staggers at this point and seems like latency but is not, similar to slowdown due to too much onscreen action but is not that either (at the check point once you first get outside).
Not played Halo 4 yet, doing games in order.
MP Matchmaking/Customs
Searching for games broken, I got around four/five games when searching these past two weeks. Kicked from party, party not kept together when matchmade games found. I had problems accessing customs after 9pm BST time.
General
Several problems experienced when trying to join friend for campaign co-op, matchmaking, customs.
Please fix, from a loyal Halo fan from the UK.
Thank you
