《獵人 ～禁斷秘寶～》（Hunter X Hunter: Kindan no Hihou）是《全職獵人》系列在Game Boy Color上推出的第二款遊戲，於 2001年4月12日由科樂美（Konami）發行。與前作《獵人的系譜》以策略RPG玩法為主不同，採用橫向卷軸的探索型動作設計，風格明顯受到《惡魔城》和《密特羅德》（Metroid）等經典作品影響，使得整體節奏與操作手感更具動作性與探索深度。雖然系統大幅轉向動作類型，但仍保留原作獵人世界的設定與氛圍，並加入念能力與角色特色，讓粉絲在動作玩法之中依然能感受到原作的魅力。

故事銜接在原作的「天空競技場篇」之後。小傑與奇犽搭乘前往鯨魚島的船隻時意外遭遇海難，漂流至一個名為「秘寶島」的神祕島嶼。混亂中兩人走散，只能各自行動並在探索途中尋找彼此。島上佈滿古代遺跡、奇異魔獸與未知的構造物，小傑、奇犽、酷拉皮卡與雷歐力必須分頭深入島嶼的不同區域，逐步揭開島上隱藏的秘密與「禁斷秘寶」的真相。劇情雖非漫畫原著情節，但原作角色間的互動與冒險氛圍依然鮮明，並且加入全新的原創角色——卡片獵人「奧格（Ogh）」——讓故事更加完整。

在玩法上，是典型的橫向探索動作遊戲。操作小傑、奇犽、酷拉皮卡與雷歐力四名角色，每個人都有獨特的能力與操作手感，並且能依冒險進度自由切換，利用各角色特性突破不同地形。小傑擅長近身攻擊與平衡發展，是最易上手的角色；奇犽的速度極快，跳躍與移動十分靈活；酷拉皮卡擁有鎖鏈能力，能攻擊遠處或開啟特殊機關，也能利用念能力進行特殊動作，使他能前往其他角色到不了的區域；雷歐力的攻擊雖未必最出色，但擁有高耐力，能在危險地形中維持穩定發揮。四人皆具備等級設定，透過擊敗敵人來提升能力，使探索過程具有成長與回饋感。

「念」在本作中扮演相當重要的角色，可視為魔法系統。能使用念來攻擊敵人、恢復體力，甚至在特定事件中以念解鎖道路或觸發機關。不同角色的念能力類型與用途也有所差異，讓戰鬥與探索更加多變。敵人方面，除了本作原創怪物之外，也能看到來自原作的魔獸登場，既能呼應粉絲熟悉的世界觀，也使關卡敵人配置更具特色。

場景種類豐富，秘寶島結構廣大，包含城堡區域、地下水路、森林遺跡、戶外山谷等多層次地圖，探索自由度相當高，各地區之間的連接與秘密通道設計明顯受到《惡魔城》系列啟發。值得一提的是，遊戲中的BOSS體型巨大，甚至在Game Boy Color的平台限制下仍展現驚人的視覺震撼，是本作的一大亮點。除主線冒險之外，還內建對戰模式，讓兩名玩家在限定時間內競爭誰能取得更多寶物。勝利者可透過轉輪獲得道具作為獎勵，並能依據玩家在主線中的進度解鎖更多角色與場景，增加遊戲重複遊玩價值。

雖然受限於掌機硬體，本作的畫面解析度與音效表現有限，但憑藉著高自由度的探索、扎實的動作手感、原作再現的角色能力與世界觀，加上豐富的地圖設計與巨大 BOSS 視覺效果，使其在發售當時於粉絲圈中獲得相當正面的評價。許多玩家認為它是Game Boy Color上少見的高品質動作探索遊戲，也是《全職獵人》系列改編作中最具可玩性與特色的一款。

整體來看，《獵人 ～禁斷秘寶～》成功將原作魅力與橫向探索動作玩法結合，提供粉絲與動作遊戲玩家一段充滿驚喜與探險精神的掌機冒險旅程，在GBC時代留下濃厚的存在感，至今仍被視為系列中最值得回味的經典作品之一。

 “Hunter × Hunter: Kindan no Hihou” (Hunter × Hunter: Forbidden Treasure) is the second Hunter x Hunter title released for the Game Boy Color, launching on April 12, 2001 and developed and published by Konami. Unlike the previous game—which focused on strategy and RPG elements—this installment shifts dramatically into a side-scrolling, exploration-based action style reminiscent of Castlevania and Metroid. Despite the genre change, the game retains the atmosphere, characters, and core concepts of the original series, blending action gameplay with the unique charm of the Hunter universe.

The story takes place immediately after the Sky Arena arc. While traveling back to Whale Island, Gon and Killua’s ship is caught in a disaster, leaving them stranded on a mysterious island known as Treasure Island. In the chaos, the two become separated. As they navigate the island’s ancient ruins, strange beasts, and labyrinthine environments, Gon, Killua, Kurapika, and Leorio must each explore different areas, reunite with one another, and uncover the secrets behind the island’s “forbidden treasure.” The plot is an original side story, but it preserves the spirit and tone of the manga, including interactions among the main cast and the introduction of an exclusive character, the card hunter Ougu, who expands the game’s narrative threads.

Gameplay centers on action and exploration. The player can switch between four main characters—Gon, Killua, Kurapika, and Leorio—each with their own strengths, movement styles, and unique abilities. Gon is balanced and easy to control, Killua excels in speed and agility, Leorio offers durability, and Kurapika uses his chains to attack from a distance or activate mechanisms that allow access to areas the others cannot reach. Each character has a leveling system, growing stronger through combat and enabling deeper exploration as the adventure progresses.

Nen plays an important role and functions similarly to a magic system. It can be used for offensive techniques, healing, or solving event-related puzzles. Each character’s Nen abilities differ, adding variety to combat and exploration. Enemies include both original creatures created for the game and beasts directly pulled from the manga, helping to maintain the worldbuilding of the Hunter universe even within this Metroidvania-style structure.

Treasure Island itself is expansive, featuring a wide range of environments including castle interiors, underground waterways, forests, outdoor cliffs, and interconnected ruins. The map design, hidden paths, and layered structure show a strong influence from classic exploration-action titles. One of the game’s standout qualities is its boss battles—many of the boss monsters are massive, especially impressive given the Game Boy Color’s hardware limitations, giving the adventure a sense of scale rarely seen on the platform.

Beyond the main adventure, the game includes a competitive versus mode in which two players race against each other to collect the most treasure within a time limit. The winner receives items through a roulette reward system. More characters and stages become available in this mode as players progress through the main story, adding replay value.

Despite the constraints of the GBC, Hunter × Hunter: Kindan no Hihou was praised for its ambitious map design, satisfying action mechanics, and faithful interpretation of the characters and world. Its blend of fast-paced combat, exploration, character switching, and massive boss encounters earned it a positive reception among fans, and it is still remembered as one of the most engaging and well-crafted Hunter x Hunter adaptations released on classic handheld consoles.
