The musical score for XCOM 2 is being composed by none other than Tim Wynn. Wynn might best be recognized for his work on Supernatural, Total War, Command & Conquer, and XCOM: Enemy Unknown.

It seems as though his work will go on sale on February 5 via iTunes and as part of the XCOM 2 Digital Deluxe Edition, which includes his soundtrack as part of the cost.
The score for XCOM 2 continues the legacy sound of the acclaimed reboot and expands the franchise's sonic palette with emotional orchestral themes and synth-driven sci-fi ambience now defined by the epic fight to take back the planet. XCOM 2 marks Tim Wynn's second outing in the XCOM universe having also written music for XCOM: Enemy Unknown.
