What gunships are you talking about?? This sound is terrible, and as the number of the air units grow, the annoying explosion sound gets greater. I mean it's not greater, it just repeats itself more and more often (like every second). Oh and by the way, I have Sound Blaster Live 5.1 card, so I don't think the problem is the sound card.... ;) So what could be this problem? I think it's a bug... there shouldn't be so much noise all the time, especially when the air units have already landed!
