You might be confused when you beat all the opponents in the Arena in Armored Core 6, and the Master of Arena trophy or achievement doesn’t unlock. However, the Master of Arena trophy/achievement isn’t bugged. You just can’t clear all the Arena programs in your first playthrough.
Why isn’t the Master of Arena Trophy/Achievement unlocking in Armored Core 6?
For beating the first 29 Arena fights in Armored Core 6, you get the Testing Complete trophy/achievement. However, you probably expect that Master of Arena will unlock as well since you get it for “clearing all Arena programs.” However, there are 12 more opponents that don’t unlock until your second and third playthroughs.
Here’s when the additional Arena opponents unlock:
