Shin Megami Tensei IV: Final‘s first trailer was recently showcased on a NicoNico livestream. It shows a first glimpse of the game’s setting, the characters, and the demons, who are a staple of the Shin Megami Tensei series. Atlus revealed some other information on the game as well. Its main theme will be monotheism vs polytheism, and will feature multiple possible conclusions to the story.
They also said that this game will feature a system where human characters are able to back each other up with “assist” attacks, which sounds very much like the mechanic used in Shin Megami Tensei IV. There are some screenshots from the livestream available too. They show off the characters, and yes, this includes the green ghost of Navarre. Shin Megami Tensei IV: Final launches on February 10, 2016 in Japan, but there is no information on a release in the West yet.
