I just beat the Horizon Finale, and if I’m not mistaking that’s where you are suppose to unlock the Horizon Chanpion Achievement. It didn’t unlock for me, wondering if anyone had this problem or if anyone knows how to fix it.
Possibly related to the server issues indicated in the announcement thread stickied at the top of the forum. Give it time, hard reboot your console, and report back if it doesn’t pop up by Monday.
Alright man, sounds good!
