Welcome to the The Chronicles of Inotia 3: Children of Carnia Wiki! The game was published by Korean mobile game developer Com2Us on January 6, 2011. Distribution of the game on the Google Play Store ended February 2017.
Since the smartphone versions of the Inotia games are actually ports from another device, this is actually only the second game in The Chronicles of Inotia series (the Korean title is 이노티아 연대기 2 : 카니아의 아이들). The game popularly known in the West as The Chronicles of Inotia 4: Assassin of Berkel is the third title in the Inotia series. In any case, each of the Chronicles of Inotia games are standalone titles and so knowledge of the previous game doesn't matter.
Initioa 3 was removed from the play store, however multiple sites still host the .apk file for it. As a result of it no longer being supported, the Adventurer's Shop cannot be used.
