Ok, for those of you following the play-by-play: I found a serviceable audio program (FREE Hi-Q Recorder) that has allowed me to get the combat audio I needed. Tomorrow will be spent doing final tweaks/sound effects and finally cutting this bad boy together into actual movie form.
Thanks for your patience. This summer's been insane, I've been slammed at every turn, running around every weekend, playing catch-up during the week, and generally out of my head for the past couple of months. With luck, I'll be back to my crappy roughly-2-month update schedule (or, hopefully, somewhat better than that) after I release this one.
