Nah, why would it be free? It's probably $10 in most of the world going by the NZ price ($15) on PSN.Will episode ardyn be free for season pass owners or do you need to pay an additional fee?
It never was advertised as part of the Season Pass - I mean, it wasn't even conceived of yet before late 2017 (and until then they weren't sure if they were going to make it as DLC, standalone game, mobile game or anime-only) and it was greenlit as DLC only in 2018. It would've presumably been part of a second Season Pass, but the Season 2 DLC was cancelled a few months ago as we know.
Guess I will whip up something simple tomorrow if I have time. Unless someone else here cares enough to do it, which I doubt, lol.
