The trailer used the music of Planetside (start listening at 0:25). I know it from tone to tone, listened it since 2006., and still listening in my car while I drive.
btw, the sms-ringtone is an "INCOMING MAX UNIT" voice macro! Funny when I have a message during a meeting.
Don Ferrone did great job with the music - I want to hear his work in PS2.
