We’ve recorded source material for the arsenal of both new and returning weapons you’ll have at your disposal in Halo 4. The gun recording was difficult because we needed to record close sounds, distant sounds, and everything in between. We had to figure out what microphone, what distance, and what range was appropriate while factoring in weather, wind, and anything and everything Mother Nature might randomly decide to throw our way.
To get the best audio quality possible, we worked with the military on one of their training grounds where the occasional dropped bomb is not an uncommon experience. During that session, we staged first-person encounters so that we could understand how the weapons should feel when playing the game, and then we used numerous 30-channel microphones to record the actual sounds.
We had to have the elements to connect the player to something familiar but still be able to offer something outlandish and alien. After this aural base is formed, we then have all the freedom in the world to mix and match different elements into a single weapon. Even a Forerunner weapon incorporates some of the elements from that gun session.
