While Killzone 2 has been seen as the PS3's graphical powerhouse since the mock trailer at E3 2005, the audio, the other half of the presentation, has largely received the cold shoulder from the press - an irony, considering the soundtrack of the first title was one of the few things that universally garnered praise from critiques.
In a recent interview, the soundtrack producer, conductor, and composer all spoke about the effort that went on behind the scenes working on Killzone 2's music score. The title is set to have 50-70 minutes of in-game music, which will change depending on the action occuring on screen, and about 30 minutes of orchastral music for use in the cut scenes. All three are very impressed by what they've come up with. Joris de Man, the returning composer from Killzone 1, went as far to say "...there were points where I was nearly weeping... [the music] was so intense".
Joris de Man also hinted at a soundtrack being available for Killzone 2. If Killzone 1 was any indication of the quality, we certainly hope there is!
