If your after some heroes/abilities, I have a Special Ops map (similar to NOTD) that I was working on (now abandoned) that has a few heroes with fully working abilities that you are welcome to copy. Just let me know if your interested and I'll send it to you (don't feel obligated to use any of it).
I was actually contemplating about whether to register my interest in giving you a hand with your project. Unfortunately my time at the moment is very limited; I have my own project which I'm working on and I'm going on holidays in a week. Maybe when I get back, I may have enough free time to give you some assistance.
Glad you liked my "Tutorial". Some of the material was ideas I got from a college course I took on Environmental Design, so I tried to focus it on map making, while keeping the ideas broad enough to be applied elsewhere.
