I don't know how many of you out there have love for the Drake or Basilisk but they could use a touch-up on their "feel"; and they could definately take note from their new cousin, the Wyvern. This may seem trivial to you, but sometimes it's the little things that count. A good audio file for a weapon can go a long way for the user experience. NB4 buried.
You know what's nice about the valkyrie? The 20mm actually sounds like you're firing an armor piercing bullet, not like you're firing farts like with the basilisk. Also, the wire-guided missile launcher sounds like you're firing some really powerful cruise missile. And on top of that, the valkyrie itself sounds great as well. In general I'd say that they did a good job with the valkyrie sounds, I just hope that the hellion and cas-14 are gonna get some great audio as well.
