Since i'm the sound editor for the mod, i can give you a bit more info on that. On the sound front we are going all out. I am working with Glare to replace ALL of the sounds in our addons starting with the Se5. This means that not only will the standard engine sound and gun shots be replace but you will also have the sound of wind wipping by your head, you will have diffrent sounds for crashing the plane into water, ground or exploding it midair. The sounds of riccocets will be changed for bullets hitting dirt, buildings, people and armored vehicals. I am going for 100% realism. each vehical will have a unique sound when it explodes or bumps into something, and you will be able to hear the wires snap on the planes wings as you crash or bits of metal fly into the air if your tank is hit...in a word, hardcore.
