It's been over a year since Final Fantasy 15 was released, but it looks like Square Enix is still adding and updating the content in the game. The December update adds the ability to swap characters at anytime, as well as a few other things.
During the latest Active Time Report from Square Enix, we received a lot of new information on the content heading to Final Fantasy 15 in December.
The 1.1.0 update due to release on December 12, 2017 will add fixes to enemies missing from multiplayer quests, character leveling, and will add additional content.
New content will include Time Limited quests where players will be matched together to defeat waves of enemies with a time limit.
FF15: Comrades will benefit from improvements as well, improving loading times and AI comrades generation times.
Later in December, Square Enix has announced that we will get more information about the upcoming FF15 DLC. The next episode in the works is Episode Ardyn, who is the main antagonist in Final Fantasy 15. This new content will provide more background on the world.
In 2018, expect even more Final Fantasy from Square Enix. Including new games, and hopefully the long awaited PC version of Final Fantasy 15!
