《戰國 Ace for Nintendo Switch》（日文原名：戦国エース，英文名：Samurai Aces）是由日本彩京（Psikyo）在1993年開發的縱向捲軸射擊遊戲，並於2018年由Zerodiv移植到Nintendo Switch平台。是彩京的初期代表作之一，也是其知名「戰國系列」的開端。保留原作的街機風格，能夠隨時隨地體驗經典的射擊操作與懷舊畫面。

設定於一個融合戰國時代與奇幻科技的平行世界。故事圍繞著神秘的「神羅教」教團，他們意圖透過古老儀式復活邪神以統治世界，並綁架將軍的女兒「月姬」作為祭品。為了阻止這場災難，六位來自不同背景、擁有各自動機的英雄踏上征途。他們分別是女忍者、武僧、陰陽師巫女、機械博士與其犬型助手、槍手與蘭斯等角色，每位駕駛獨特的飛行器，搭配個性化的攻擊方式與特殊技能，共同對抗愈加強大的敵人與最終的邪神。

操作方面延續經典街機的簡潔設計，主要透過方向鍵控制移動，並搭配射擊與炸彈兩顆按鍵完成所有動作。透過收集強化道具提升武器等級，最多可升級至第四段，但最強火力狀態會隨時間逐漸衰減。此外，遊戲設有蓄力射擊系統，只需按住射擊鍵即可發動角色專屬的強化攻擊。共設有七大關卡，前半部會隨機選擇出現順序，後半則固定流程，關卡節奏緊湊且變化多端。BOSS設計亦相當有彩京風格，充滿誇張造型與激烈彈幕。

在Nintendo Switch上的表現方面，獲得不少熱愛懷舊射擊遊戲玩家的好評。忠實還原原版街機風貌，同時藉由Switch的便攜特性讓玩家能夠隨時展開短時間的挑戰。雖然難度偏高，新手可能需花時間適應彈幕與敵人行為模式，但整體節奏緊湊、操作流暢，十分適合喜歡硬派射擊挑戰的玩家。音效與音樂方面也延續90年代街機的風格，帶有濃厚懷舊氛圍，角色配音與中日式融合設定更為整體增添不少趣味。

總體而言，《戰國 Ace for Nintendo Switch》是既復古又充滿個性風格的射擊遊戲代表作，無論是對於當年有街機記憶的老玩家，或是對日式彈幕射擊感興趣的新世代玩家而言，都具備吸引力與挑戰性。其獨特的戰國科幻世界觀、豐富的角色選擇與經典的遊戲設計，讓這款誕生於90年代的名作，在今日的遊戲平台上依然展現出不容忽視的魅力。

Samurai Aces for Nintendo Switch (Japanese title: 戦国エース) is a vertical scrolling shoot-’em-up originally developed by Japanese studio Psikyo in 1993. In 2018, the game was faithfully ported to the Nintendo Switch by Zerodiv, bringing this early arcade classic to modern audiences. As one of Psikyo’s foundational titles, Samurai Aces also marks the beginning of their well-known “Sengoku” series. The Switch version retains the original arcade aesthetics, allowing players to experience classic shooting gameplay and nostalgic visuals anytime, anywhere.

The story unfolds in a parallel world that blends Japan’s Sengoku period with fantastical steampunk technology. The central narrative revolves around a mysterious cult known as the Shinra Sect, which plans to revive an ancient evil god through a forbidden ritual. To achieve this, they kidnap the general’s daughter, Tsukihime, to use her as a sacrificial offering. In response, six heroes from vastly different backgrounds and motivations set out to stop the cult and save the world. These characters include a female ninja, a warrior monk, a shrine maiden onmyoji, a mechanical scientist with his dog-shaped robot companion, a gunslinger, and a mysterious lancer. Each pilot operates a unique flying machine, complete with distinct attack patterns and special abilities, adding depth and variety to the combat.

In terms of gameplay, Samurai Aces stays true to its classic arcade roots with a simple and responsive control scheme. Players use the directional pad to move and rely on just two buttons: one for shooting and one for bombs. Weapon upgrades can be collected during stages, enhancing firepower up to four levels. However, the highest weapon level gradually weakens over time, encouraging constant engagement. A charge attack system is also implemented, allowing players to unleash powerful character-specific attacks by holding down the fire button. The game features seven stages, with the first half randomized and the latter half set in a fixed sequence, keeping the gameplay fresh with varying enemy arrangements. True to Psikyo’s design style, boss battles are over-the-top, with creative mechanical designs and intense bullet patterns typical of the company’s “bullet hell” flair.

On the Nintendo Switch, Samurai Aces has been well-received, particularly by fans of retro shooters. The game faithfully reproduces the arcade experience while leveraging the Switch’s portable nature for quick, on-the-go sessions. Although the difficulty is notably high, which may pose a challenge for newcomers, the tight pacing and smooth controls make it an engaging choice for players who enjoy hardcore shooting challenges. The sound design and music remain true to the 1990s arcade style, contributing to the game’s nostalgic charm. The fusion of traditional Japanese and steampunk elements, along with voiced characters, further enriches the overall experience with a quirky and unique flair.

In summary, Samurai Aces for Nintendo Switch is a standout title that blends retro appeal with distinctive artistic flavor. Whether you’re a veteran gamer reminiscing about arcade glory days or a newcomer interested in exploring the world of Japanese bullet hell shooters, this title offers both charm and challenge. Its imaginative Sengoku sci-fi setting, diverse cast of characters, and classic gameplay design prove that this 1990s gem still holds strong appeal on modern platforms.
