《東京地下殺手》（Tokyo Underground Killer）是由Phoenix Game Productions 開發，並由3DM Games與Gone Shootin發行的第一人稱動作遊戲，於2025年9月 5 日在Steam平台推出。以虛實交錯的近未來東京為舞台，將霓虹閃爍的都市風景與黑暗暴力的地下世界結合，打造出一段充滿血腥、速度感與風格化的刺客傳說。主角「小林」（Kobayashi）是以吸血鬼之力為武器的暗夜殺手，他必須在活死人與黑幫橫行的東京地下社會中殺出一條血路，迎戰以「Flatliners」為名的殘暴組織，並用鮮血重寫這座城市的命運。

在劇情氛圍的塑造上，強烈帶有賽博龐克與哥德恐怖的混合氣息。小林作為「新宿吸血鬼」，既是都市傳說，也是黑暗世界的夢魘。他在東京標誌性的街區，如新宿、秋葉原與澀谷之間遊走，對抗惡鬼般的活死人軍團以及各式殘酷的黑幫分子。故事中穿插大量漫畫風的狂氣敘事，由漫畫家Hans Steinbach（筆名：重金屬半藏）負責繪製超過80頁的故事內容，畫面呈現出既像遊戲又像地下漫畫的獨特風格。

操作與玩法方面，核心圍繞「刀鋒戰鬥」與「血技系統」。以武士刀「樹木子」進行刺擊、斬擊與連續閃避，並結合吸血鬼的特殊能力進行殲滅。戰鬥節奏快如電光火石，需要穿梭於群敵之中完成暗殺與處決。擊殺敵人後可吸取鮮血，補充生命與血技能量，並觸發十餘種不同的血技效果。除此之外，提供七種槍械與十三種特殊能力，能靈活切換戰鬥風格，在槍火與刀光之間展現殘酷又爽快的動作張力。

《東京地下殺手》並不僅止於血腥的戰場，還營造獨特的都市日常感。在完成任務後能返回新宿公寓休憩，並透過打工、購物、轉蛋、玩夾娃娃機等活動，體驗霓虹東京的潮流文化。偶像周邊、樂團唱片、模型與海報都能收集與擺設，在血腥之外也能享受輕鬆的自訂樂趣，體驗黑暗與日常並存的荒誕氛圍。

在市場評價與期待度上，自公布以來便吸引大量關注。其獨特的吸血鬼題材結合賽博龐克風格，以及Unreal Engine 4打造的霓虹城市質感，在第一人稱動作遊戲中脫穎而出。戰鬥設計被認為既殘酷又暢快，血技與吸血機制帶來與眾不同的戰鬥循環。再加上Andrew Hulshult（曾為《Dusk》《毀滅戰士：永恆》譜曲）操刀的兩小時以上電子音樂原聲，強烈的聽覺衝擊與視覺風格，使其被玩家視為2025 年Steam上最值得期待的黑暗系動作新作之一。

Tokyo Underground Killer is a first-person action game developed by Phoenix Game Productions and published by 3DM Games and Gone Shootin, set to launch on September 5, 2025, on Steam. Set in a near-future Tokyo where neon-lit cityscapes collide with a violent criminal underworld, the game tells a blood-soaked, fast-paced, and stylized tale of an assassin. Players take on the role of Kobayashi, a vampire hitman who wields the power of blood as a weapon. To survive the lawless underground society overrun by gangsters and the undead, he must carve a path of destruction through the brutal Flatliners gang and ultimately rewrite the city’s fate with blood.

The narrative atmosphere blends cyberpunk aesthetics with gothic horror. Known as the “Shinjuku Vampire,” Kobayashi is both an urban legend and a nightmare haunting the city’s darkest corners. He prowls iconic Tokyo districts such as Shinjuku, Akihabara, and Shibuya, facing hordes of demonic undead and ruthless gang enforcers. The story also features a strong manga influence, with over 80 pages of illustrated content created by comic artist Hans Steinbach (pen name: Heavy Metal Hanzo), giving the game a unique hybrid style that feels like both a video game and an underground comic book.

Gameplay centers around blade combat and the blood technique system. Kobayashi’s primary weapon, the katana “Jumokuji,” allows for thrusts, slashes, and swift evasive maneuvers, enhanced by his vampiric powers to decimate foes. Combat is lightning-fast, requiring players to weave through enemy swarms to execute assassinations and finishers. Defeated enemies provide blood, which restores health and refills the blood arts meter, unlocking over a dozen unique abilities. Alongside melee combat, players can wield seven firearms and thirteen special powers, enabling seamless transitions between brutal swordplay and high-caliber gunfights, amplifying the game’s visceral intensity.

Beyond the carnage, Tokyo Underground Killer also embraces a slice-of-life urban experience. Between missions, players can return to Kobayashi’s Shinjuku apartment, rest, and immerse themselves in Tokyo’s vibrant street culture. Activities include working part-time jobs, shopping, capsule toy hunting, or playing claw machines. Collectibles such as idol merchandise, band posters, figures, and records can be displayed, offering a contrast of lighthearted customization against the backdrop of blood-soaked violence.

Since its reveal, the game has generated significant buzz. Its fusion of vampire lore with cyberpunk visuals, powered by Unreal Engine 4, makes it stand out in the first-person action genre. Combat has been praised as both savage and exhilarating, with the blood arts and vampiric feeding mechanics adding a refreshing twist to traditional gameplay loops. Combined with a two-hour-plus original electronic soundtrack composed by Andrew Hulshult (Dusk, DOOM Eternal), the game promises a sensory experience as stylish as it is brutal. Many players and critics alike view Tokyo Underground Killer as one of the most anticipated dark-action titles to arrive on Steam in 2025.
