Evaluation

Sixtar Gate: STARTRAIL officially launched on December 30, 2024, after a period of Early Access development. Since launch, the developer has maintained a consistent pattern of updates including collaboration DLC packs, free music additions, and feature patches. The most recent major content update shipped on August 6, 2025, with the KALPA: Cosmic Symphony collaboration DLC pack. The developer has continued communicating actively beyond that, with feature patches and bug fixes running through August 14, 2025, and a development status post on June 30, 2026. That June 30, 2026 post is particularly significant: the developer confirmed that a new collaboration DLC pack is currently going through review and is scheduled for release in mid-to-late August 2026, alongside additional OUTER SPACE Mode courses and other game mode improvements. They acknowledged an internal roadmap restructuring but were clear that new content is on the way. The store description also explicitly states that new tracks from franchises like VOCALOID and Touhou Project are planned for future addition, and that Adventure Mode remains in development. All 9 DLC packs listed on the store are released, but the developer has plainly communicated that more content is coming imminently.

About this game

Sixtar Gate: STARTRAIL, a different kind of rhythm game, is now available on Steam! From humble beginnings, something truly grand will be born! Let us enjoy this experience as we work together to create a fresh new rhythm game!

■ Meet your charming navigator

Explore the vast Sixtar system on the science vessel Ausflug with your partner Shii, the operator of the vessel.

Adventure mode, allowing players to get a glimpse into the story of Sixtar Gate, is currently in the works.

■ Check out the variety of music we have to offer!

Featuring songs from artists any rhythm game fan would recognize, including Life is PIANO, Brain Power, and CO5M1C R4ILR0AD.

We have also included original songs from artists like Sound Souler, KARUT, and yomoha that can only be heard in Sixtar Gate: STARTRAIL.

In the future, we are planning to introduce new tracks from well-known franchises like VOCALOID and Touhou Project that players would not easily find in other rhythm games.

■ The gates are opening!

Gates open and close with the flow of the song, changing the amount of lanes players will have to pay attention to.

Experience a new kind of rhythm game. The implementation of this gate system means that you won't be able to let your guard down for a single instant.

■ Free-form multiplay : Unity Session

It doesn't matter if you're not good at rhythm games or just want to play your favorite songs, or even just want to listen to music!

Play and interact with everyone at the same time without limit in one place!
