Development of "Devil May Cry 4" began shortly after its predecessor was a success. A total of eighty people formed the development team. The first teaser was that of Dante on a snowy peak shown at E3 2005, while the Tokyo Game Show 2005 trailer showed Dante doing multiple moves in front of a camera, both containing elements that were not included in the finished product. Capcom only made the E3 2005 video to confirm their staff had begun work on the game. Since they had just finished "Devil May Cry 3" and "Devil May Cry 3: Special Edition", the developers initially were confused in regards to what they had to do in order to innovate the gameplay mechanics they developed previously. The team wanted to introduce new gameplay elements and a new character allowed them to do this. This was the first "Devil May Cry" not to be released for PlayStation 2, because it was designed for the next generation of hardware. This allowed the team to try new play mechanics and expand the series' plot. While not intending to send a religious message, members from the Capcom team did research in Vatican City and Istanbul.
