Walkthroughs for custom maps.

Creating heroes of level 6424 is a fairly common practice.

Is it common among Chinese players? :) I'm still avoiding such maps: I haven't reached the level where I can understand them yet. :)
In WoG, this can be implemented using scripts (or by replacing the files with unit characteristics). On one puzzle map, there's a "super peasant" with skills better than a blue dragon.
