If I recall, the intro is tied to a west soldier, and if no one is playing west, the intro won't work right. I just started making missions when I made that, and the intro is not as elegant as I can do now lol.
I have made many other missions, some serious, some just fun. You are welcome to come play on the USI server to see some of my maps, or I can send them to you also.
My Night Forest Fight is popular, set in the trees, at night, a nice small ctf. My adaptation of Tequila Sunset, made in to a CTF, is also very popular on our server, and others. I also made a race map using the dune buggy add ons. One of my favorite maps is called Subdivisions, set on winter nogojev. I also made another 3 sided map, king of the hill mission, which I like a lot. I will email that to you in a minute. As all map makers know, or will learn, only maybe 10 percent, if your lucky, of the maps you make, will be popular, no matter how good you think they are, that's just the way it goes. Happy make making!
