Shin Megami Tensei IV: Apocalypse is a 2016 role-playing video game developed and published by Atlus for the Nintendo 3DS. It is the sequel to Shin Megami Tensei IV, set in a post-apocalyptic alternative world. The game is part of the Shin Megami Tensei series, the central series of the Megami Tensei franchise. The game features gameplay mechanics from previous Shin Megami Tensei releases, such as the Press Turn battle system, where players and enemies fight and exploit weaknesses, allowing either side to gain additional turns or lose them.

The story follows an alternative timeline to that of Shin Megami Tensei IV, and focuses on the demon hunter Nanashi, a silent protagonist who dies and is resurrected by the demon Dagda.
