I have completed a whole new XL-sized two-layer (2x overworld) map for my HOMM III map pack after a half year in making. There were times when I worked with it more constantly, while sometimes more rarely.
The new four (4) team eight (8) player map is now at the stage where I feel that it's playable, and tested well-enough for me to put it up for grabs! I apologize for any spelling errors, as English is not my main language. The event-heavy map with quite many surprises is playable with Inferno, Fortress, Dungeon, and Rampart, can be downloaded as part of my whole HOMM III map pack from the original post featuring the map pack as whole. Find the dowload link here. Check it out. Also, feel free to let me know what I could improve in the map making!
