Atlus shared the English and Japanese versions of the Shin Megami Tensei 30th anniversary logo, and each one features iconic demons like Jack Frost and Pixie. The only difference between the two logos is the text. Otherwise, they are identical.
Pixie is sitting on the bottom of the “3” in 30 for the Shin Megami Tensei 30th anniversary logo, while Jack Frost is hanging off of the “0.” Pyro Jack is positioned above Jack Forst, right next to the “H” in “30th.” Decarabia is right in front of him. There is also another demon right about the “3” that looks like it could be Orthrus.
The most recent Shin Megami Tensei entry was SMT V. It appeared on the Nintendo Switch in 2021. Ahead of that, SMT III: Nocturne HD Remaster showed up for the PS4, Switch, and PC.
Atlus hasn’t announced any new games or projects to tie in with the Shin Megami Tensei 30th anniversary yet. The original SMT appeared on the Super Famicom in 1992 in Japan. The game didn’t appear officially in English until its 2014 iOS debut. In Japan, it joined the Nintendo Switch Online library of free games for subscribers back in 2020.
