The Demon Tower has a minimap.
In the center of the Demon Tower, there are skeleton objects that I don't think exist in the current version of the Demon Tower.
None of the maps in the game feature a spot for the horses, which means there was no mount system back then. Starting with the 2005 client, there are locations on the map for horses.
The bridges were probably very narrow back then, but very long.
Back then, there were three maps for Orc Valley. In the current game, the map belonging to the Red Kingdom is used by everyone.
Back then, the following Orc Valley maps were used for the Blue and Yellow Kingdoms:
Some map called Field Dungeon
The following map was likely one of Ymir's very first test attempts, given that it bears the simple name "metin2_map." I believe this map has already been posted here a few times.
