Despite having been playing the game extensively and exclusively since 1.05 dropped on Xbox none of the achievements have ever dropped.
I have met the criteria for most of them, have been using an official server, have swapped servers and met achievement criteria and it still doesn't pop.
Meet any achievement criteria and it fails to unlock.
Met the criteria for the following:
Bodily needs
Geared
Act of mercy
Baby-face
Pacify
On multiple occasions during different respawns.
I have been playing since the 1.04 update and have been having the same issue, no achievements are unlocking on Xbox. I've tried uninstalling and reinstalling the game and playing on alt accounts but nothing works.
