《首都高賽車》（Tokyo Xtreme Racer）是以未來東京為背景的街頭競速遊戲，將玩家置於一個被封鎖的都市高速公路網中，駕駛自豪的改裝車追求最快速度，以登上頂點為目標。高度還原東京首都高速環狀線的賽道，每一段彎道、每一次高低落差都力求貼近現實，讓人彷彿置身於真實的夜間高速競速場景中。不僅要與其他車輛擦身而過，還需要面對各種強大且具有個性化駕駛風格的對手，每場對決都充滿緊張與刺激，精神壓力幾乎達到極限，這也是該系列作品長期吸引玩家的重要魅力之一。

遊戲操作方面，引入獨特的SP戰鬥（Spirit Point Battle）系統。與一般單純比拼速度的競速遊戲不同，SP戰鬥將駕駛者的精力值量化，必須在高速駕駛中精準運用策略來削減對手的精力，單靠速度並不足以取勝，思維與心理戰術的運用同樣至關重要。這種機制增加遊戲的策略層面，使比賽不再單調，而是每一場對決都具有高度變數與挑戰性。

遊戲中的對手設計充滿神秘感和個性魅力，他們擁有不同特色的車輛以及獨特的駕駛風格。比賽開始的信號是一道閃光燈，玩家需要在瞬間判斷對手的行動並做出反應。這種設計不僅增加遊戲的沉浸感，也讓每次競速都像是一場心理與技術的雙重較量。

自2025年9月25日在Steam平台發行以來，憑藉精緻的賽道還原、獨特的SP戰鬥系統以及高度緊張刺激的駕駛體驗，獲得玩家與媒體的廣泛關注。許多玩家稱讚遊戲將街頭競速與策略元素結合得淋漓盡致，特別是夜間高速公路的駕駛場景，被認為是目前街機風格競速遊戲中少有的高度真實呈現。同時，對於追求自訂改裝車的玩家而言，遊戲提供充足的改裝與調校選項，使每輛車都能展現個人風格。

此外，《首都高賽車》的PlayStation 5版本預定於2026年2月26日發售，屆時將進一步提升畫質與操作手感，並可能加入更多賽道與對手。整體而言，這款遊戲在市場上被視為競速遊戲迷必玩的作品之一，其結合速度、策略與心理博弈的玩法，使得它在競速遊戲類型中擁有獨樹一格的地位。

Tokyo Xtreme Racer is a street racing game set in a sealed-off, futuristic Tokyo, placing players on the city’s intricate network of highways where they race customized cars to achieve the fastest times and reach the top. The game meticulously recreates the Tokyo Shuto Expressway, capturing every curve, slope, and elevation change to provide a realistic night-time racing experience. Players must weave through traffic, face powerful opponents, and manage high-pressure, adrenaline-filled races, which is a signature element of the series’ enduring appeal.

The gameplay introduces a unique SP Battle (Spirit Point Battle) system, which sets it apart from standard racing games. Instead of relying solely on speed, players must monitor and strategically deplete the opponent’s Spirit Points—a numeric representation of their willpower—while maintaining control of their own vehicle. Success depends not only on driving skill but also on tactical thinking and psychological maneuvering, making each race a combination of high-speed action and strategic depth.

Opponents in the game are designed with distinctive personalities, unique vehicles, and bold driving styles. Races start with a flash of headlights, signaling players to react instantly and engage in tactical maneuvering. This adds a layer of immersion and challenge, turning each encounter into a dynamic test of both skill and strategy.

Since its release on Steam on September 25, 2025, the game has been praised for its faithful track recreation, innovative SP Battle system, and intense, immersive racing experience. Players have highlighted the night-time expressway setting as one of the most realistic representations in modern arcade-style racing games. Additionally, the robust vehicle customization system allows players to tune and modify their cars to reflect their personal style.

The PlayStation 5 version of Tokyo Xtreme Racer is scheduled for release on February 26, 2026, promising enhanced graphics, smoother controls, and potentially new tracks and rivals. Overall, the game is widely regarded as a must-play for racing enthusiasts, offering a unique combination of speed, strategy, and psychological competition that sets it apart in the racing game genre.
