Decade Dungeon Gaiden, a new MSX RPG game by HABIT SOFT (JP) | By MSXALL

Game Plot

Adventurer, I often visited you. On the outskirts of this city, there is a decaying dungeon, and it is said that treasures sleep deep underground. However, there are many evil monsters lurking, and there are countless adventurers who have exhausted themselves in the dungeon. If you still want to challenge yourself, be prepared. May you have the blessing of God!

How to Play

Explore the dungeon while defeating monsters and leveling up. The treasure chest contains valuable items. Watch out for mimics while trying to defeat the boss monsters hidden in the bottom layer. Once you have the jewels, return to the entrance. It's a dungeon crawl until you get home!

  • When you defeat a monster, you will gain experience points and level up. As you level up, the maximum life value will increase and your life will be restored. If the maximum life value does not increase, the life will be restored to a large extent.
  • You can get the item by taking the treasure chest. In rare cases, mimics mimic a treasure chest.
  • Go down the stairs and aim for the bottom layer. If you move the floor, the displayed map will be reset.
  • There is a boss monster in the bottom layer. When you defeat the boss monster, a treasure chest containing jewels will appear.
  • Once you have the jewels, go up the stairs and return to the entrance to the dungeon. It will be clear if you can return safely.
