Aegis: The First Mission

Aegis: The First Mission is a 2007 action role-playing video game developed and published by Bbmf. It is a prequel to Atlus's 2006 game Persona 3, and part of the Persona series, itself a part of the larger Megami Tensei series. It was originally released for Japanese feature phones in October 2007, after which it became unavailable for years and was considered lost, until G-Mode's re-release for Nintendo Switch and Windows as part of their G-Mode Archives+ line in June 2024.

The story takes place ten years prior to the events of Persona 3, and follows the humanoid robot Aigis as she battles enemies during an incident at the Kirijo Ergonomics Research Laboratory on the Japanese island Yakushima. The game was well received for its action gameplay, story, and visuals, particularly for the aesthetics of the environments.
