Fans of Shin Megami Tensei IV (SMTIV) will be thrilled to know that the website for the newest entry in the series finally has its first screenshots in English. However, if you have never played the previous game, be careful, as this article does contain some links that can potentially spoil the previous game.
The story of this particular game is explained here:
The Demons page in particular shows of many demons that are potential allies and enemies, and explaining their involvement in the previous game. The Systems page goes more into the gameplay mechanics, such as combat, recruiting demons, and many other features for those curious about what is in SMTIV Apocalypse. Fans of the previous title will be glad to know many things appear to be unchanged from the original, such as equipment changing your appearance, the Smirk system, demon recruiting and fusion, and much more. There is far more, and you check them all out by accessing the website here.
SMTIV was originally released in North America on July 16, 2013, developed and published by Atlus. The sequel, Apocalypse, was originally called Final before the name changed, and takes place during the events of SMTIV. SMTIV Apocalypse is set for release in North America in the summer of 2016, and Amazon.com currently has a pre-order date set for September 20, 2016.
