I am looking for maps for Heroes III.

I was specifically wondering whether to explain why I didn't do it myself in 5 minutes. What I saw: it wasn't a map made up of 3-4 resources; instead, it was an XL-sized map with a lot of different things packed into it, meaning you could test almost anything: from taking a Necropolis to drowning units under various conditions. That's why I'm asking about it. Why reinvent the wheel when it's already been invented? I assumed that something similar already existed on the forum, but I haven't had a reason to spend time here, so I'm not very familiar with it, which is why I had to ask for help.
