於1991年7月25日在Neo Geo街機基板（MVS）與家用主機（AES）上推出的《聖十字劍》（Crossed Swords / クロスソード），是由SNK發行、Alpha Denshi（ADK）開發的早期代表性動作作品之一。在當時以橫向捲軸與格鬥遊戲為主流的市場環境中，大膽採用極為罕見的「主觀後視角」（玩家角色背對鏡頭）來呈現戰鬥，並以半透明線框構成主角輪廓，使玩家既能感受到自身存在，又不會遮蔽前方敵人的動作。這種設計不僅帶來強烈的視覺衝擊，也為動作遊戲引入嶄新的距離判斷與防禦策略，成為Neo Geo初期最具實驗性與辨識度的作品之一。

在基本表現與整體氛圍上，充分發揮Neo Geo硬體的動態縮放與多層背景技術。敵人會從遠方逐步逼近，隨著距離拉近而不斷放大，營造出極具壓迫感的臨場戰鬥體驗。與同樣採用主觀視角的《諜報飛龍》相比，本作將重心完全轉向冷兵器對決，並進一步強化戰鬥節奏與判定精度。遊戲美術融合厚重的西洋中世紀盔甲風格與奇幻怪物設計，場景從荒廢村落、幽暗森林延伸至宏偉城堡，層層推進出一段史詩般的征途。配樂則以帶有交響感的電子音為主，搭配金屬碰撞與盾牌格擋的清脆音效，使整體氛圍更顯莊嚴且充滿戰意。

故事發生在名為「貝魯提亞（Belitner）」的王國。邪惡魔神奈特梅亞（Nausiz）率領亡靈軍團入侵人界，使原本繁榮的國度陷入黑暗與混亂。玩家扮演奉國王之命出征的傳奇劍士，手持聖劍與盾牌，踏上橫越七個被詛咒領地的遠征之旅。沿途將遭遇垂死求援的村民、提供指引的智者，以及鎮守各地的巨大魔物。隨著戰線逐步推進，敵軍勢力愈發強大，而玩家也逐漸逼近最終決戰的核心——魔神的王座。整體敘事雖然遵循傳統英雄史詩的架構，但透過關卡推進與敵人設計，成功營造出一種由絕望走向光明的征戰歷程。

在操作系統方面，最具革命性的地方，在於它將「防禦」提升至與攻擊同等重要的核心地位。必須透過搖桿控制盾牌的高低位置，精準對應敵人的攻擊方向。當敵人進行上段斬擊時，必須抬盾防禦；若對方改以低位突刺，則需迅速下壓盾牌格擋。成功防禦後，敵人會出現短暫破綻，這時才是揮劍反擊的最佳時機。這種講求節奏與判斷的戰鬥方式，使遊戲更接近擊劍對決，而非傳統的連打型動作遊戲。除此之外，玩家還能透過蓄力或消耗能量施放強力魔法，例如閃電或火焰攻擊，以應對大量敵人或高強度戰鬥情境。同時融入輕度RPG要素，擊敗敵人可獲得金幣與經驗值，並可在關卡間強化裝備或更換不同特性的武器，讓整體冒險更具成長感與策略深度。

在市場評價方面，獲得極具特色且偏向核心玩家的高度評價。評論普遍肯定其創新的視角設計，認為它成功突破傳統2D遊戲在空間表現上的限制，讓玩家能真切感受到敵人迎面攻擊的壓力與距離變化。那種劍鋒直逼眼前、成功格擋後反擊制敵的快感，為當時的動作遊戲帶來全新的體驗層次。

然而，本作也因其高難度而聞名。敵人AI具備相當的攻擊節奏變化與誘敵能力，對玩家的反應速度與判斷力要求極高，使得新手容易在初期遭遇挫折。但正因如此，它也被許多資深玩家視為極具深度與挑戰性的作品。整體而言，《聖十字劍》被公認為Neo Geo時期最具「硬派美學」的代表之一，不僅在視角運用上具有開創性，也為後來動作遊戲在空間與防禦機制上的發展提供了重要啟發。即使歷經多年，它依然在復古遊戲愛好者心中佔據著不可取代的地位，成為一段關於劍與榮耀的經典傳奇。

Released on July 25, 1991, for the Neo Geo arcade system (MVS) and home console (AES), Crossed Swords (クロスソード) is one of the early flagship action titles published by SNK and developed by Alpha Denshi (ADK). At a time when side-scrolling beat ’em ups and traditional action games dominated the market, this title stood out by adopting a highly unusual “rear-view perspective,” placing the player’s character in a semi-transparent outline at the center of the screen. This allowed players to maintain a sense of presence without obstructing their view of incoming enemies. The result was a striking visual presentation that introduced a new sense of spatial awareness and defensive strategy to the action genre.

From a technical and atmospheric standpoint, Crossed Swords made full use of the Neo Geo’s sprite-scaling capabilities and multi-layered backgrounds. Enemies approach from the distance and gradually enlarge as they close in, creating an intense sense of depth and pressure. Compared to other experimental titles of the era, the game refined its combat into a focused melee system centered on swords and shields. Its visual style blends heavy Western medieval armor aesthetics with dark fantasy creature design, while environments range from ruined villages and shadowy forests to imposing castles. The soundtrack features symphonic-style electronic compositions paired with the sharp metallic sounds of clashing weapons, immersing players in a dramatic world of steel and sorcery.

The story takes place in the kingdom of Belitner, a once-prosperous land now plunged into darkness by the invasion of the demon lord Nausiz and his undead army. Players assume the role of a legendary swordsman tasked by the king to embark on a perilous journey across seven cursed territories. Along the way, they encounter dying villagers, wise figures offering guidance, and massive guardians standing in their path. As the journey progresses, the forces of darkness grow stronger, leading ultimately to a final confrontation at the demon lord’s throne. While the narrative follows a classic heroic quest structure, it effectively conveys a sense of progression from despair to hope through its stage design and escalating encounters.

What truly defines the gameplay of Crossed Swords is its emphasis on defense as an equal counterpart to offense. Players must actively control the height of their shield using directional inputs, matching the level of incoming attacks. High strikes require raising the shield, while low attacks demand a downward guard. Successfully blocking an enemy’s attack creates a brief opening for a counterstrike, making timing and precision essential. This rhythm of defense and retaliation gives the game a dueling quality, more akin to fencing than to conventional hack-and-slash action. In addition to standard attacks, players can unleash powerful magic such as lightning or fire by consuming energy, offering crowd control options in more intense battles. The game also incorporates light RPG elements, allowing players to earn gold and experience, upgrade equipment, and choose different weapons between stages, adding a layer of progression and strategy.

In terms of reception, Crossed Swords earned a distinctive reputation and was especially appreciated by hardcore players. Critics widely praised its innovative perspective, noting that it overcame the spatial limitations of traditional 2D games and delivered a uniquely immersive combat experience. The sensation of enemies attacking directly toward the player, combined with the satisfaction of a perfectly timed block and counterattack, set it apart from other action titles of its time.

However, the game is equally known for its high difficulty. Enemy AI frequently varies attack patterns and employs feints, requiring sharp reflexes and careful observation. This steep learning curve can be daunting for newcomers, but it is precisely this challenge that has made the game a favorite among dedicated players. Overall, Crossed Swords is regarded as one of the defining examples of Neo Geo’s “hardcore” design philosophy. Its pioneering use of perspective and its disciplined combat system left a lasting impact, securing its place as a classic that continues to be admired by retro gaming enthusiasts today.
