I’m having issues with this achievement unlocking in Halo 3 ODST.
This was completed in co-op (I wasn’tthe host) with all 3 other gamers getting the achievement but me.
The other thing to note is all difficulty achievements remained at “100% unlocking” for nearly 2 weeks!
I’ve tried loading the prologue in legendary and completing a level in legendary but still nothing.
Does anyone have any suggestions?
