Volcano High Bulletin

The Volcano High Bulletins are a series of newsletters created as glimpses into the development of Goodbye Volcano High, released roughly monthly preceding the game's release, which covers a myriad of topics, from the processes used for development, to game teasers, to the latest promotional efforts from KO_OP. The newsletters generally have multiple perspectives, with a mix of both characters from the game as well as sections from KO_OP; the in-universe portions are generally written by Marcela, though the rest of the cast may make appearances as well.
