Zup! X

Zup! X is a compact casual puzzle game that launched on May 17, 2018 with 60+ levels and 2880 achievements. The store description presents it as a fully self-contained product with no mention of planned updates, DLC, or ongoing content. There are no DLC listings for this game and no developer posts about adding content to Zup! X specifically. The developer news from this game's page is largely composed of announcements for entirely separate games released by the same studio — including Zup! Y, OxU, OxU 2, CubeOS, and others. The Zup! series appears to follow a model where each numbered entry is its own standalone, complete product rather than a game that receives ongoing updates. Zup! X fits that pattern: it launched as a finished product and has not received post-launch content updates. The developer, Quiet River, remains actively creating new games (most recently OxU 2, released February 1, 2026), but that ongoing studio activity does not indicate any forthcoming content for Zup! X itself.
