Thanks for the responses all!
Flashy, thanks for your suggestion. I have done this a couple of times, and can do this ok, but would rather not have to get two bases up and run all the time, it's a bit stressful...
TH300, I'll see what I can do in the mapper. I have worked with it a few times, but could not understand all that had to be done. However, with what you have told me, I will see what I can do, and then send you a map file.
Once I have a completed Map, what would I do to be able to play it in game?
Also, I would enjoy playing this game with other people. I don't personally care for 'Last Man Standing' types, but would play that. With this game, leisure play is more fun to me.
