 In an interview with Polygon, producer Hisashi Koinuma and Omega Force CEO Hideo Suzuki mentioned that a key focus was on making the AI more intelligent, as well as making the game more difficult in comparison to the first title.They've also worked closely with the manga's publisher Kodansha and writer Hajime Isayama in the creation of additional elements to the story.Initially the English voice cast were going to record dialogue but this was not realised due to time constraints, very much like the first game.
