Who composed the soundtrack for the original Assassin's Creed game?

Jesper Kyd composed the soundtrack for the original Assassin's Creed game.

Kyd's score combines orchestral writing with electronic textures and atmospheric choral sounds. The music supports the game's contrast between medieval cities, tense assassination missions, and the mysterious science-fiction framing story involving Desmond Miles.

The original game was released in 2007 and follows Altaïr Ibn-La'Ahad during the Third Crusade. Kyd's work helped establish the series' musical identity, especially its use of ominous ambience and dramatic themes during exploration and combat.

Other composers later became closely associated with the franchise. Lorne Balfe composed music for Assassin's Creed III and contributed to later entries, while Sarah Schachner worked on Assassin's Creed Origins and Assassin's Creed Valhalla. Those later credits do not change Kyd's role on the first game.
