Albeit Final Fantasy 15 might not have been a major hit among long-time fans of the Final Fantasy franchise, I personally thought it was a really accessible and enjoyable game. It has a good story, nice graphics and it plays really well too. However, the game is far from perfect and has quite a few annoyances. Confusing controls and dull level design being the most complained about.
Apart from those annoyances there are also massive plotholes: Nearing Chapter 6 (about halfway through the game), one of your party members leaves you behind in order to “sort some stuff out”, but the standard game never reveals what happened. Well, March 28 that mystery will be solved. Episode Gladiulus is a DLC package that will expand the story of Gladio. The teaser released by Square Enix reveals he will have to battle with the recurring villain Gilgamesh. Some other interesting things one can see in the trailer is that Gladio will able to use a pillar as a weapon, as well as an updated HUD.
More information about this package will undoubtedly be released as we near the release date. You can check the trailer below.
