Ultimate Coaster X

Ultimate Coaster X launched into Early Access on March 10, 2019 as a free roller coaster simulator. Five days after launch, on March 15, 2019, the developer posted a feature patch and included a roadmap outlining what remained before a 1.0 release — including additional train types, better sound effects, graphical fixes, and crash resolutions. That post is the only developer communication on record. There have been no further updates, patch notes, blog posts, or announcements of any kind since March 15, 2019. The game has remained in Early Access for over seven years with no public sign of ongoing development. The 1.0 goals described in that roadmap do not appear to have been fulfilled, and the developer has not communicated whether the project is still active.
