Which composer wrote the main musical score for Assassin's Creed II?

Jesper Kyd wrote the main musical score for Assassin's Creed II.

Kyd's score combines orchestral writing, choral textures, electronic sound, and period-inspired color to support the game's Renaissance Italian setting. The music helped define the atmosphere of Ezio Auditore's story, moving between intimate themes, exploration pieces, and tense sequences.

Assassin's Creed II was released in 2009 and expanded the series far beyond the first game's setting. Its soundtrack became especially associated with Ezio and with the recurring theme often identified as Ezio's Family, which was later rearranged and reused in several franchise entries.

Later Assassin's Creed games used different primary composers. Lorne Balfe scored Assassin's Creed III, while Sarah Schachner worked on Origins and Valhalla. Those composers are connected to the series, but Jesper Kyd is the answer for Assassin's Creed II.
