《地下礦工2》（UnderMine 2）是由美國獨立開發商Thorium Entertainment製作並發行的動作類Roguelike遊戲，是前作《UnderMine》的正統續作。延續前作廣受好評的2D橫版地下城探索風格，並在此基礎上大幅擴展遊戲內容、世界觀與角色養成系統，堪稱系列的全面進化。

故事發生在神秘而危機四伏的德爾韋莫城堡（Delvemore Castle）周邊。這是陷於陰謀與惡魔侵蝕中的古老王國中心，主角是原本平凡的農夫，被命運推入地底世界，在一層層地下礦井中對抗邪惡勢力，揭開古老魔法、王權鬥爭與被封印力量之間的謎團。

劇情融合幻想與政治陰謀，描繪人類、惡魔與各方勢力之間的衝突與合作。在每次深入地牢的過程中，將逐步拼湊出整個世界的真相，並最終面臨選擇命運的時刻。不同的選擇與探索路線會觸發分支劇情與多種結局，讓劇情不再只是背景，而是影響遊戲走向的核心。如果挑戰過程死亡就會損失所有物品跟部分殘留現金，原本的級數與能力不會有所改變，但須用另一個農民身分重新開始。

繼承Roguelike的核心設計理念，所有地牢皆由程序生成，每次遊玩都有全新的地形、敵人與資源配置，確保高重玩性與挑戰性。遊戲依然採用2D橫向動作風格，搭配清晰的打擊手感與豐富的技能組合，讓操作既直覺又充滿深度。需在地下挖掘黃金、聖物與藥水等資源，同時與多樣化的怪物交戰。戰鬥過程中可靈活運用閃避、遠程攻擊、法術與陷阱等多種戰術手段，尤其在高難度區域與 Boss 戰中，需合理運用技能與資源管理，方能生存。

新增阿卡那（Arcana）聖物系統，這是具有互動性的魔法技能樹，可使用火球術、召喚骷髏、時間操控等能力來強化戰鬥風格。聖物之間可自由搭配與合成，創造出極具個人特色的戰術流派，從最初的「一無所有」成長為最終的「深淵英雄」。此外，新增多名可操作角色，每位角色都有獨立的技能樹與專屬能力。例如新角色「黑兔」是一名擅長勾索與快速移動的寶藏獵人，適合敏捷與陷阱流派；而原初的農夫角色則更擅長力量與生存。角色之間差異明顯，也讓玩家在不同周目中嘗試各種戰鬥風格。

首次加入雙人合作模式，支持本地分屏與線上聯機。與朋友共同挑戰地牢，並面對隨之動態調整的敵人強度與關卡設計。例如某些Boss需要雙人同步觸發弱點、互補技能破解特殊機制，或在限定時間內合作解開謎題，提升遊戲的互動性與策略深度。合作模式並非僅是增加人數，而是設計為真正需要配合與溝通的冒險體驗。雙方可搭配不同角色與聖物組合，創造出超越單人模式的戰術體系，適合好友共同挑戰高難度內容。

自發表以來便受到原作粉絲與Roguelike愛好者的高度期待。上市後獲得多數正面評價，玩家普遍肯定其在前作基礎上所做的進化，包括更豐富的劇情設定、更高自由度的聖物組合、角色系統的多樣性以及合作模式的創新設計。在Steam、Epic等平台上評價多為「極度好評」，尤其受到喜愛挑戰性遊戲的玩家青睞。不少評論指出，作品成功兼顧硬核與休閒的平衡，在提供足夠深度與策略性的同時，也保留爽快的操作體驗與幽默風格，讓人「一玩就停不下來」。

整體而言，《地下礦工2》不僅是優秀的續作，更是對Roguelike地牢探索類型的一次精彩再詮釋。其豐富的玩法機制、多樣的角色養成與細膩的合作設計，讓這部作品在眾多獨立遊戲中脫穎而出，成為2025年不容錯過的佳作選擇。

UnderMine 2 is an action Roguelike game developed and published by the U.S.-based indie studio Thorium Entertainment. It serves as the official sequel to the acclaimed title UnderMine, building upon its popular 2D side-scrolling dungeon-crawling mechanics while significantly expanding its content, world-building, and character development systems. This entry is widely regarded as a comprehensive evolution of the series.

The story unfolds around the mysterious and perilous Delvemore Castle, the decaying heart of an ancient kingdom plagued by dark conspiracies and demonic corruption. Players take on the role of an ordinary farmer, thrust by fate into the treacherous depths below, battling sinister forces and uncovering long-buried secrets of magic, royal power struggles, and sealed ancient evils.

The narrative blends high fantasy with political intrigue, portraying the complex dynamics between humans, demons, and various factions. As players descend deeper into the ever-changing mines, they gradually piece together the truth behind the world’s chaos. The choices made and the paths taken influence how the story unfolds, leading to branching plotlines and multiple endings. Death in a run results in the loss of all collected items and a portion of gold, though character levels and permanent upgrades remain intact. However, the next expedition begins with a new miner, reflecting the cyclical nature of the challenge.

UnderMine 2 remains faithful to the core of Roguelike design: procedurally generated dungeons ensure that each run offers a fresh layout of terrain, enemies, and resources, maintaining high replayability and challenge. The game retains its signature 2D side-scrolling action format, enhanced with tight, responsive controls and a rich variety of skill combinations, delivering intuitive gameplay with strategic depth.

Players must mine for gold, collect relics and potions, and fight off a wide range of enemies. Combat involves agile dodging, ranged attacks, magic, and traps. In tougher zones and boss battles, strategic skill usage and resource management become essential for survival.

A major innovation in this sequel is the introduction of the Arcana system, an interactive skill tree built around magical relics. Players can acquire and combine abilities such as fireball casting, skeleton summoning, and time manipulation, offering highly customizable combat builds. The freedom to mix and merge relics allows players to craft unique fighting styles and transform from a humble peasant to a true “Abyss Hero.”

The game also introduces a diverse roster of playable characters, each with distinct skill trees and exclusive abilities. For example, the new character Black Rabbit is a treasure hunter skilled in grappling and rapid movement, ideal for agility- and trap-focused playstyles. The original farmer, by contrast, specializes in strength and survivability. These unique traits encourage varied strategies across different playthroughs.

For the first time, co-op gameplay is included, supporting both local split-screen and online multiplayer. Players can team up to tackle dungeons together, facing dynamically scaled enemy strength and challenge mechanics. Certain bosses require cooperative timing to expose weaknesses, while others demand skill synergy or puzzle-solving within tight time limits, deepening the game’s tactical complexity.

This co-op mode is not just an added feature—it’s a thoughtfully crafted experience that demands real coordination and teamwork. With diverse character and relic pairings, players can craft strategies that go far beyond what’s possible in solo mode, making it an ideal game for friends seeking high-stakes cooperative action.

Since its announcement, UnderMine 2 has garnered significant anticipation from fans of the original and Roguelike enthusiasts alike. Upon release, it received largely positive reviews, with players praising its expanded lore, the freedom of relic customization, the depth of its character system, and the innovation of its co-op mode. On platforms like Steam and Epic Games, it holds a “Overwhelmingly Positive” rating, especially favored by those who enjoy challenging, strategic gameplay. Many reviews highlight its successful balance between hardcore depth and casual accessibility, retaining the crisp controls and quirky humor that made the original so addictive.

Overall, UnderMine 2 is not just a worthy sequel—it’s a masterful reimagining of the Roguelike dungeon-crawling genre. Its rich mechanics, character diversity, and well-designed cooperative systems make it stand out among indie titles in 2025, earning its place as one of the year’s must-play games.
