Second Collection is a CD release in the vein of the previously released Shin Megami Tensei: Devil Summoner Demon Compendium. Like the former title, Second Collection features higher resolution demon graphics for the 300+ demons appearing in the titular Devil Summoner: Soul Hackers. Along with this demon artwork is commentary on the demons themselves. Unlike the previous compendium, this CD also features a sound novel that details the story of Spookies' formation. There was also a sound room allowing players to listen to the background music of Soul Hackers.
