Shin Megami Tensei IV (Japanese: 真・女神転生IV ") is a Japanese post-apocalyptic role-playing video game developed by Atlus for the Nintendo 3DS. It is the sixth entry in the Shin Megami Tensei series, a spin-off from the Megami Tensei franchise, though no direct story connection exists to previous entries. It was released in May and July 2013 for Japan and North America respectively. It was released digitally in Europe in October 2014. The gameplay is reminiscent of previous Shin Megami Tensei games, carrying over the turn-based Press Turn battle system, where players and enemies fight and exploit weaknesses, gaining or losing turns depending on whether or not they strike weaknesses.
