The Great Ace Attorney Chronicles includes three alternate costumes for the main characters that were previously part of the Japanese DLC releases. These costumes can be used during gameplay, allowing for a personalized courtroom experience.

While many modern games treat costumes as mere skins, the Ace Attorney series has a long history of using alternate outfits to add levity and character depth. The DLC brings "The Three Great Collections" to the forefront: The Student, The Artisan, and The Adventurer.

While these are cosmetic, they are implemented with care. Capcom has ensured that the pixel art for these costumes is just as detailed and animated as the default outfits, making them a joy to use during long investigation segments.

The cosmetic costumes can be enabled immediately. They do not affect anything beyond aesthetics.
