Between February 25 and March 16, 2016, Capcom ran a promotional campaign on their Japanese Twitter account called the "Everyone! Support Tweet Campaign" by encouraging fans to post a tweet or retweet using the hashtag "#逆転裁判6応援" (Gyakuten Saiban 6 Support). The rewards for the campaign included smartphone wallpapers of Phoenix, Apollo, and Athena, with an 8-minute long anime prologue that would not be included in the game being the highest goal at 18,000 hashtags. This threshold was quickly surpassed, with the final count reaching 55,589 hashtags and being rewarded with an additional wallpaper of Maya.
