The game will be available as a free download, featuring the first two cases from Phoenix Wright: Ace Attorney available to start.
Users will then be able to purchase individual cases or entire game bundles from the first game as well as from its sequels Phoenix Wright: Ace Attorney Justice for All and Phoenix Wright: Ace Attorney Trials and Tribulations.
Capcom used a similar release plan for Ghost Trick earlier this year, and priced the full game at £7 / $10 after playing the included free stages.
Each game will be enhanced with high definition visuals, redrawn for the iOS version based on the original Nintendo DS sprites.
In addition to the three games, the iOS release will include the Everybody Object mode, letting users email and tweet signature phrases like "Objection!", "Hold it!", and "Take that!" complete with their in-game animations.
Phoenix Wright: Ace Attorney HD Trilogy does not yet have a release date, nor is Capcom discussing the pricing for cases at this time.
