You should notice that this tutorial is quite huge, that`s because it lays out a lot of basic principles which you will need for all future maps. I hope this isn`t TOO big for you all but I feels it`s needed to make sure you dont get lost and that you end up knowing what the hell you`ve just done. A lot of you will want to refer to this tutorial again and again, don`t worry, it took me ages to get to grips with all the ideas here, but once you have them, you will fly through all the more advanced tutorials.
