Through Abandoned: The Underground City

Through Abandoned: The Underground City is a completed point-and-click adventure game that launched on July 22, 2015. It is described explicitly as "the first part" of the Through Abandoned series, with a sequel — Through Abandoned: The Refuge — released on March 25, 2019. That sequel release was announced via the game's own news feed, confirming the series continued as planned. The last meaningful update to this specific game was a technical overhaul on February 11, 2019 (version 1.01), which rebuilt the game on Unity, added Full HD support, and expanded language options. No further content updates have been posted since then. The more recent news posts on this game's Steam page (from 2024–2025) are publisher announcements for entirely unrelated games under the Conglomerate 5 / Valkyrie Initiative publishing umbrella — none of them relate to this title. There are no unreleased DLC entries, no roadmap promises, and no developer statements indicating further content is planned for this game. The original 2016 announcement of a sequel has been fulfilled by The Refuge's 2019 release. This game launched as a self-contained adventure and has been complete since the series continued with its sequel in March 2019.
