Walkthroughs for custom maps.

I've been playing "Heroes" for a while now, and I still didn't know that events in cities can not only add, but also remove troops! Although, I haven't seen a map where this happens yet.

I think this is done using an advanced map editor. In the regular editor that I use, you can see the negative values, like in my screenshot, but I don't know how they were set. And for some reason, the game displays an increase of 65,000 creatures every week.
