Summon Night 3 is the third installment in the Summon Night series, which combines elements of tactical RPGs with sci-fi and fantasy settings. The game takes place on the planet of Astera, where humans and a variety of alien species coexist. Players control a party of characters as they explore dungeons, battle enemies, and uncover the secrets of the planet.

The Summon Night series has a dedicated fan base, but the lack of an official English translation limited its reach. The creation of an English patch for the PSP version of Summon Night 3 is a significant milestone, as it allows players worldwide to experience the game in their native language.

The patch, created by a team of dedicated fans, translates all in-game text, including character dialogue, menu options, and item descriptions. The patch also fixes several bugs and issues present in the original Japanese version.
