About Sixtar Gate: STARTRAIL
Sixtar Gate: STARTRAIL is a rhythm game released on Steam for Windows. Players travel the Sixtar system aboard the vessel Ausflug, accompanied by the navigator Shii, while tapping notes that match the music.
The title features a dynamic “gate” system that changes the number of active lanes during each song, and it offers single‑player, online co‑op, and a free‑form multiplayer Unity Session where any number of players can join.

Gate System
Gates open and close in sync with the music, altering the number of lanes that players must watch. This mechanic ensures that attention is required throughout each track, as lane layouts can shift at any moment.
The gate system is highlighted as a core innovation, differentiating Sixtar Gate: STARTRAIL from static‑lane rhythm titles and demanding continuous adaptation from the player.
- Watch the gate animation early in a song to anticipate lane changes.
- Practice on slower tracks to become comfortable with lane variability.

Free‑form Multiplayer (Unity Session)
The Unity Session allows unlimited players to gather in a single space, regardless of skill level. Participants may play, simply listen, or interact while the same song plays for everyone.
This mode removes performance pressure, making the experience accessible to newcomers and casual listeners who want to enjoy the music together.
- Join a Unity Session even if you only want to listen; it can help you learn patterns before playing.
- Invite friends to create a shared listening party for a relaxed experience.
