GameSpy.com's Soldier of Fortune II Developer Diary Volume 5 offers more sound thinking from Raven's Zachary Quarles, the sound designer on Soldier of Fortune II: Double Helix. In this installment, after relating the fact that he feels he is going insane with temporary voice-over recording/placement, Zach goes on to relate his inspirations for designing a piece of game music, discussing the added complications caused by SoF2's dynamic sound system. The diary also has a batch of Soldier of Fortune II sounds for download, and FilePlanet also has the SoF2 trailer and the John Mullins video interview from the SoF Platinum edition.
