I've been working on this project for a very long time. It is not finished, and I'm uploading it so people may be able to finish what I started. It is more or less a Hack & Slash module.
I couldn't figure out how to set up the overland map spawning, so there is none. There are a few areas that when you happen to come into contact with an overland map creature, if you accept to fight them, you'll be teleported to one of these areas to fight the group of creatures that spawned on the map. For example, if you encounter a Beholder, you will be teleported to an area with several Beholders to fight.
This is a Campaign, so when you go to play it, remember to access the module through the " Campaign" menu.
There are several "areas" to explore: caves, towers, and other buildings. The recommended starting level is 15. Most of the creatures in the module are at least level 15, so be prepared. There is no auto-leveling script, which would be a nice addition.
My favorite part of this whole campaign is the Overland Map - I love it. The campaign is kind of a sandbox style module, where you just go around, kill stuff, collect gold, treasure, and bounty items. There is an NPC in the Inn somewhere on the Overland Map, that buys the bounty items. There is no end to the module, just continue hunting. It might be fun to play it with some other people, but I have not tested it with otherplayers.
Well, I hope you guys enjoy this Campaign/Module. I'm open to feedback, help, and suggestions. Just remember, I am a Mapper, NOT a Coder. If you are able to help finish this, I'm more than happy to get the input. Have Fun!
