Episode Gladiolus is the first piece of DLC content for FFXV, and it really shows. It is a DLC that has big ambitions, but is just too short to really see those ideas shine. The DLC follows Gladio as he briefly leaves the main part in the middle of XV's story. He leaves with an older royal guard named Cor, and together they go into the lair of the ancient Royal Guard of the first king of Lucis, Gilgamesh. The main content of the game is just a couple of action set pieces where you fight a couple waves of enemies and descend further into the cave to challenge Gilgamesh and prove yourself as a worthy shield to King Noctis. Gladio himself plays really well all things considered as he is slower than Noctis, so his combat focuses on pacing yourself and parrying at the right time. When you master Gladio's play style the DLC really shines, and it's put on full display during the battle against Gilgamesh himself and the bonus fight with Cor. Sadly like I mentioned outside of those two instances the DLC doesn't really take the time to challenge the player in any meaningful way which is truly a shame. Luckily as the DLC kept coming out the content got better as the development team were willing to experiment... for the most part.
