DoDonPachi Resurrection

DoDonPachi Resurrection launched on Steam on October 13, 2016, as a port of an existing arcade/console game. All four DLC items — four soundtrack releases — shipped between October 2016 and March 31, 2017. There are no unreleased DLC entries on the store. Post-launch developer activity was concentrated entirely in the first few months after release: a handful of bug fixes and feature patches were issued between October and November 2016, and the last soundtrack DLC shipped on March 31, 2017. The two news posts categorized as major content (NEWS-1 and NEWS-2) from December 2021 are announcements for entirely different games published by the same publisher (Crimzon Clover World EXplosion and Castle of Shikigami 2), not updates to DoDonPachi Resurrection itself. The most recent post that actually concerns DoDonPachi Resurrection dates to November 2016 (NEWS-3/NEWS-7, a development status note saying "we've not forgotten" base game updates, and a follow-up patch in November 2016). There have been no further game updates, announcements, or developer communications about this title since early 2017. The game shipped as a feature-complete port with a defined set of modes and content, and the developer never established a pattern of ongoing post-launch content additions beyond the initial soundtrack DLCs.
