available as downloads on Xbox Live. The initial release contained a corrupt patch that would not install and had to be requested separately from Ubisoft, after which they would send a CD-R with the patch. The bonus disc can also be obtained with the GameCube version by contacting Ubisoft.com via e-mail. The Xbox version also contains the XBL missions on disc 2, which can be installed on the PC version of the original Splinter Cell. Soundtrack Chaos Theory – The Soundtrack to Tom Clancy's Splinter Cell: Chaos Theory is the fifth album by Brazilian electronic music artist Amon Tobin. It was released on January 25, 2005, by Ninja Tune. Seminal composer Jesper Kyd was also hired to score the game's cinematics. The album consists of a collection of songs Tobin wrote for the game. Ubisoft was so pleased with Tobin's work that they decided to release the album several months ahead of the actual game. In-game music sequences are similar but not identical to the official soundtrack, as most in-game music is produced by layering different sequences together. This album showcased the beginning of Tobin's shift from collecting samples from vinyl records to recording his samples. For the recording of Chaos Theory – Splinter Cell 3 Soundtrack, Tobin hired a live band whose members ranged from Mexican composer Nacho Mendez to Japanese flutist Eiji Miyake.

Tobin would more fully explore the use of his samples by using field recordings in the following 2007 album, Foley Room.

Rob Semsey of TeamXbox gave the game 9.8 out of 10 and said,
