Everyone: Every Battle in the Diamonds of the Kobolds: Kobold Warriors Kobold Avengers Kobold Spearmen Every Battle in the White Star: Kobold Warriors Kobold Avengers Kobold Spearmen Kobold Priest / Pokkin Also the tutorial scenarios might have the similar problem. (haven't confirmed this)
I really enjoy the ambience in those kobold levels (reminds me for some reason of Fallout Tactics and Inon Zur) and in the Defense of Woodhome. I'd wish more levels had the same athmospheric sounds. Also the battle against Greenfang has cool music that really gets you going. It would be cool if it would be playing against Xanthicius. (why not also Blizkenripper)
