2022: A Doom Odyssey is a complete Boom-compatible Ultimate Doom replacement with a total of 5 episodes, created as a team effort by Paul Corfiatis alongside with long-standing collaborators Kristian Aro and Christian Hansen.

It's less of a direct sequel to the 2002ADO but moreso a broad retrospective on all the previous stand-out projects the team has been involved with, an ultimate heartfelt tribute to the original game and fun memories it brought.
