The X4: Envoy Pack Soundtrack includes 10 tracks created by long-time X series composer Alexei Zakharov and newcomer Alexei Galygin. This collection moves between calm, atmospheric pieces that build tension, and more powerful, energetic tracks that capture the stakes and shifting alliances at the heart of the X4: Envoy Pack expansion (Release: September 10, 2025).

This soundtrack accompanies the X4: Envoy Pack expansion, enriching the in-game experience. By purchasing the soundtrack, you gain access to the music outside of the game in high-quality MP3 and FLAC formats, while also supporting Egosoft's work on the X series.
