It's fun! That's probably the most I can say about this one. I adore Gladio as I do the rest of the boys, so I enjoyed the extra time with him. I really like how he plays mechanically, and the final boss and optional boss are both engaging, testing your understanding of how combat has worked thus far and rewarding you accordingly. It's short, and it's not very complex- especially compared to the other FFXV DLC episodes- but it's not bad by any means. I don't know if it justifies a purchase, but it is enjoyable for a piece of add-on content, hindered mainly by the fact that it is in fact optional, paid content. The gratuitous amount of Gladio ass shots are pretty fucking worth it though, I'd say.
