Yes, Citadel: Forged with Fire is now released with version 1.0, which a post on the Steam page notes has added four new Mastery-level weapons. The same post also further promises to continue to listen to player feedback and address bugs in the near-term while adding previously offered updates in the long-term, including epic quest lines, dye systems for clothing and structures, new weapons, mini-boss world events, and more.
