《未來戰士》（RYGAR）是由TECMO於1986年推出的經典橫向卷軸動作街機遊戲。以其獨特的武器設計和富有挑戰性的關卡設計，在當時的遊戲市場中佔有一席之地，並成為許多玩家記憶中的經典。Lynx版本略有不同，總共包含23個關卡。此作品後來被收錄在Xbox平台的《Tecmo Classic Arcade》合輯中，同時也在Wii Virtual Console上販售。

故事發生在經過45億年的未來地球。在歷經許多不同的領導長時間控制後，屬於他們的時代紛紛落幕。在19XX年，由頭目Rygar (Ligar) 領導的恐怖生物軍團突然出現，試圖掌控整個世界。苦不堪言的人們把所有希望都寄託在一個預言的降臨，相信來自阿爾格斯的戰士將再次重返人間，對抗邪惡大軍。

遊戲總共有27個關卡，每個舞台都有時間上的限制。一開始有兩台數，玩家操控傳說中的勇者進行戰鬥，武器是可伸縮攻擊的盾牌。跳躍在敵人頭上可以使其暫停。隨著關卡的進行，後續可以獲得五種裝備進行強化。

使用方向鍵配合攻擊與跳躍兩個按鈕。主要武器是名為「戰盾（Diskarmor）」的鍊盾，它可以向前投擲攻擊敵人並在擊中後自動返回，類似於回旋鏢的設計。不僅能擊退敵人，還能用於破壞障礙物或激活機關。這種獨特的武器設計成為遊戲最大的亮點之一，在戰鬥中能夠同時保持攻擊與防守狀態。隨著關卡推進，還能獲得各種道具與強化裝備，使戰盾的攻擊範圍與威力逐漸提升，增加遊戲的深度與策略性。

關卡設計方面，擁有多個風格迥異的場景，涵蓋古代遺跡、森林、火山、地下洞穴及天空之城等。每個關卡都充滿挑戰，需要精準跳躍，閃避敵人與陷阱，並在面對大型頭目戰時展現操作技巧。關卡中隱藏著許多秘密路徑與寶物，仔細探索才能發現，這也讓整體的耐玩度大幅提升。採用多層次的場景設計，有時需要垂直攀爬或在不同平面之間來回穿梭，打破傳統橫向卷軸遊戲的單調性。

每個關卡的尾端通常設有強大的頭目，這些頭目不僅擁有巨大的體型與特殊攻擊模式，還需要觀察其行動模式並找出弱點才能順利擊敗。擊敗頭目後，會獲得新的能力或道具，為後續的關卡探險鋪路，逐步解鎖新的區域。

市場評價方面，當年在街機市場推出後迅速獲得廣泛關注，其獨特的遊戲機制與華麗的視覺風格吸引大量玩家。當時的遊戲機台經常排滿等待挑戰的玩家，成為TECMO在街機市場的成功之作。評論普遍認為遊戲性與視覺表現上均處於領先水平，尤其是戰盾系統的創新設計，使其在眾多橫向卷軸動作遊戲中脫穎而出。然而，部分玩家指出遊戲的難度較高，特別是後期關卡的敵人密集度與複雜的地形設計，對操作要求較高，容易讓新手感到挫折。但對於喜愛挑戰的玩家而言，這正是該作品吸引人的地方，提供極大的成就感與探索樂趣。

"Rygar" is a classic side-scrolling action arcade game released by TECMO in 1986. With its unique weapon design and challenging stage layouts, it held a notable place in the gaming market at the time and became a cherished classic in the memories of many players. The Lynx version differs slightly, containing a total of 23 stages. The game was later included in the "Tecmo Classic Arcade" compilation for the Xbox platform and was also available on the Wii Virtual Console.

The story takes place on Earth, 4.5 billion years in the future. After long periods of rule by various leaders, their eras gradually came to an end. In the year 19XX, a legion of monstrous creatures led by the boss Rygar (Ligar) suddenly emerged, attempting to seize control of the entire world. Desperate, the people placed all their hopes in a prophecy foretelling the return of a warrior from Argus to battle the forces of evil.

The game consists of 27 stages, each with a time limit. Players control a legendary hero equipped with a shield capable of extending for attacks. Jumping on enemies' heads temporarily immobilizes them. As the game progresses, players can obtain five different types of equipment to enhance their abilities.

In the arcade version, collecting special items grants invincibility. Each stage has a time limit, and treasure chests appear at specific points. The game uses a 2D side-scrolling format, where players move from the left to the right endpoint to clear the stage. Players can use stone piles to avoid enemies that jump in fixed patterns.

The game controls involve a directional pad and two buttons for attack and jump. The primary weapon is a chained shield called the "Diskarmor", which can be thrown forward to attack enemies and returns automatically after hitting its target, similar to a boomerang. The Diskarmor not only repels enemies but can also destroy obstacles or activate mechanisms. This unique weapon design is one of the game's major highlights, allowing players to attack while maintaining a defensive stance. As players advance, various items and power-ups can be collected to extend the Diskarmor's attack range and increase its power, adding depth and strategy to the gameplay.

The stage designs feature diverse environments, including ancient ruins, forests, volcanoes, underground caves, and sky castles. Each stage is full of challenges, requiring precise jumps, enemy evasion, and trap navigation. Boss battles demand skillful maneuvering and observation of attack patterns to uncover weaknesses. Hidden paths and treasures are scattered throughout the stages, rewarding thorough exploration and significantly enhancing replayability. Multi-layered stage designs often require vertical climbing or traversing between different planes, breaking the monotony of traditional side-scrolling games.

Most stages conclude with a powerful boss, each possessing massive size and unique attack patterns. Defeating these bosses requires players to study their movements and exploit weaknesses. Upon victory, players receive new abilities or items that unlock access to subsequent areas, gradually paving the way for further exploration.

Upon release, the game quickly garnered widespread attention in the arcade market. Its unique mechanics and striking visuals attracted a large player base, with arcade machines frequently crowded with players eager to take on the challenge. Critics praised the gameplay and graphics, noting the innovative Diskarmor system as a standout feature that distinguished it from other side-scrolling action games.

However, some players found the game to be quite difficult, particularly in later stages where enemy density and complex terrain demanded precise controls, potentially frustrating beginners. Nonetheless, for players who enjoyed a challenge, this was part of the game's appeal, offering a sense of accomplishment and excitement in exploration.

The overall difficulty is lower than that of the NES/Famicom version. The arcade version remains regarded as the most challenging and iconic, reappearing in several retro game compilations and nostalgic gaming consoles over the years. It continues to influence action game design and remains a legendary title cherished by a generation of players.
