Rubinite Soundtrack Guide

Rubinite Soundtrack on Steam

Cup Dog Games released the Rubinite Soundtrack (紅眼露比 Soundtrack) as standalone Steam DLC alongside the July 22, 2026 launch. The OST sells for $4.99 USD separately or bundles with the base game under “Rubinite & Soundtracks BUNDLE” on the store page. Steam Family Sharing applies to purchased DLC the same way it applies to the main game.

Guardian Faye’s battle theme became a breakout favorite during demo coverage — Gamemeca and Rock Paper Shotgun both highlighted how Faye’s music pacing shapes dodge rhythm. Retail adds additional boss themes and Cathedral hub ambience beyond the two demo fights. The release trailer embedded below previews the score’s dark fantasy tone across Scarlet Kingdom arenas.

What the OST Covers

The Steam DLC listing describes the soundtrack as the complete score for Rubinite’s nine-boss base campaign plus Cathedral hub vignettes. Track titles follow in-game boss and region names — community playlists on YouTube and Spotify may appear post-launch as Cup Dog Games or GameWorks Ventures publish official uploads.

Buying the OST supports the Taiwanese indie team behind Rubinite without requiring a second playthrough. If you cleared the campaign and want Faye’s theme on repeat during work sessions, the DLC is the intended legal route rather than ripping game files.

Bundles and Sale Timing

During the introductory 10% launch sale until August 5, 2026, the base game drops to $17.99 from $19.99 — the soundtrack price stays $4.99 unless Steam runs a separate music sale. Steam also lists cross-promo bundles pairing Rubinite with Death’s Door and Titan Souls at additional bundle discounts for souls-like fans discovering Cup Dog Games through launch week coverage.

The 2nd East Asia Indie Games Celebration (EAIGC) sale begins August 5, 2026 — the same day the introductory discount ends. FilterGame and participating Taiwanese studios may feature Rubinite again during EAIGC; watch the Steam news feed for a second discount window if you missed launch week pricing.

Listening Outside the Game

Steam’s built-in music player and the Steam mobile app can stream purchased soundtrack files once the DLC is in your library. No separate launcher is required. If you prefer lossless archival, check whether Cup Dog Games publishes Bandcamp or Qobuz links in future store updates — none were confirmed as of July 29, 2026.
