EDIT: To make this post worthwhile, the one thing that I don't really like are the clear musical cues, for, say, what I've lovingly dubbed a 'Horn rush'. I'd love it if the music kicked in just as they attacked, or about half a second before, but as it is now you have a good three or four seconds to get in position so that you can easily defend against the impending swarm. I know you can turn the music off, but I like the music. I don't like the warning. :\
