Final Fantasy 15’s next story expansion, Episode Ignis, will launch Dec. 13.

Sony showed a new trailer during the pre-show for Paris Games Week this morning. Just as Episode Prompto and Episode Gladiolus gave Noctis’ other bros their starring turns, Episode Ignis will do the same for the smartest member of the group.
