Keeper of the Hidden Treasure: Zombie Game - A Look at the Rarest Dungeon Crawl I Own

About 秘宝の番人ゾンビゲーム (Keeper of the Hidden Treasure: Zombie Game), from BoardGameGeek:

This is a game designed by Ginichiro Suzuki, and produced by Epoch. It is a game where you are exploring the underground, uncovering treasures, and fighting monsters, all in an attempt to get to the castle and have the most treasure. Hailed as a Masterpiece in Japan. It is not so much the game, but the art of Ritta Nakanishi that makes this game so popular. Ritta is noted for his military illustrations and military model art. This game is fully illustrated from top to bottom (well, not the bottom of the box) with his wonderful art featuring all sorts of horror. In addition, the entirety of the box is used. In fact, there are four tops/lids that are illustrated and used in the game. The result is a three-dimension board where the players move through different levels. There are even pitfalls at the highest level, as well as caves, in addition to foldable terrain pieces. To top this off, there is a facade that fits to the back of the board featuring the game's objective. All this creates a highly immersed game experience. From the box cover: The zombies have awakened, and the greatest terror of the century is upon you! The warning bell is ringing! The evil clutches of the zombies are closing in! If you don't escape quickly, you'll turn into a zombie! —user summary
