Some screenshot from the story dungeon.
The story dungeon will be the direct continuation of the last cutscene with the generals. After some time, you will get contacted by them and they will help you find Mr. White (The old way of reaching him will be removed from the game). They will refuse to take you there if your weapon skills and physical stats are too low. In later versions, there will be more ways to reach Mr. White, many of which will not require combat.
The dungeon it self will be pretty linear with plenty of dialogue explaining some lore bits and giving more personality to the generals and one other NPC that will acompany you. Dungeon will end with a boss fight and you will meet Mr. White after that. You will give him the letter and get more lore and dialogue.
After that, he will act just like he did before. Selling equipment and training you. The dungeon in the basement will also be locked and you will need a special key to open it. He will give it to you. The event for getting certain number of humanoid kills will also be different.
Work is progressing smoothly. I still have some tiles to make and I will have to make a lot of dialoge and eventing, but I'm slowly getting there.
