I have been playing some of the Anniversary lists the past couple of days to score the achievements.
I believe I have fulfilled the requirements for some of the achievements a few times now but they are not popping.
Specifically -
Infection be the Last Man Standing
I get the medal for last man standing but not the achievement in this game

Get a beatdown medal while jetpacking - I’ve done this loads of times now - the Firebird medal comes up and the beatdown medal but no achievement
Twice in this game

Honestly I don’t like playing infection. I really, really, really don’t. My k/d was 2.33 overall and it is dropping badly as I don’t like the gametype and the continued Infection / Betrayal issue is still there. Infection is so unbalanced, so broken.
I hate using Jetpack also. The only MM medals I have ever earned for the AA are due to trying to get this achievement.
Honestly I think I am going to boost these achievements due to the failure of the MM system to recognize something I have achieved. I know then I will probably be banned but I am sick of it.
