Codex Gamicus

Apollo Justice: Ace Attorney, released in Japan as Gyakuten Saiban 4, is a visual novel video game for the Nintendo DS. It is the fourth video game in the Ace Attorney series.

Apollo Justice is the first game in the series to be developed specifically for the DS as opposed to being a port of a game originally for the Game Boy Advance. As such, the DS' touch screen and microphone features are a fundamental part of Apollo Justice.


Apollo Justice is the first game in the series not to feature Phoenix Wright as the main protagonist, though it is not the first time a different attorney has been playable. A limited edition of the game was made available for the Japanese release on April 12, 2007. It includes branded headphones, a Gyakuten Saiban Dictionary on a DS card, and a series highlights DVD.

Localization title

The new game no longer features Phoenix Wright as the protagonist, as the previous three games did. Capcom's previous naming for the translated games has included the localized name of "Phoenix Wright" as the protagonist in the title for these games. A photo taken from a Nintendo Europe event which included a banner for the game confirmed that the protagonist, Housuke Odoroki, is localized as "Apollo Justice", with the game title being Apollo Justice: Ace Attorney. This was confirmed when the English trailer for the game was presented at the 2007 Tokyo Game Show.
