Ok so the other night (12/12/12) I managed to pop this achievement, it shows up on my Xbox and also on Xbox.com but it doesn’t show up on Waypoint… Do some achievements take longer to load or will this now never show up (as I can’t get it ever again).
Cheers in advance.
I don’t know, i just have 49/49 achievements despite getting some of the newer ones from Crimson.
Of course, all i did to earn ODST was race a Hog straight into another one at full speed. It was one epic explosion 
Haha yeah all I did to get it was jump off a ramp and shoot someone mid air. Things don’t seem to be going to flash with all these achievment things, I thought this sort of stuff was tested.
They havent added those ones to Waypoint. I read this somewhere but they said they will be adding them later
Ahhhh ok makes sense, went on an achievement spree last night, was disappointed when it didn’t show up
