由BANDAI NAMCO Studios Inc.開發、BANDAI NAMCO Entertainment發行的《緋紅結繫》，於2021年問世，是一款以「腦內龐克（Brain Punk）」為核心美學的超腦力動作RPG。作品結合高速戰鬥、深度劇情與雙主角敘事，打造出一個科技極度發達卻充滿危機的未來世界。

故事背景設定在人類腦部能力高度開發的近未來都市「新日向」。在這個時代，人類透過科技將大腦潛能轉化為各式各樣的超能力，文明因此飛躍發展。然而，世界同時也遭受名為「怪異」的異形生命體威脅——牠們自天而降，專門吞食人類的腦部，且對傳統武器幾乎免疫。為了對抗這種無法理解的存在，人類組建了由精英超能力者構成的「怪異討伐軍（OSF）」，肩負守護社會的重任。

玩家將在兩位主角之間展開旅程：一位是因童年被拯救而立志加入OSF的熱血少年「結人皇」，另一位則是天賦異稟、冷靜理性的少女「重蘭德爾」。兩人同樣擁有強大的「念力」，卻從不同立場與視角切入這個世界。隨著戰鬥與任務推進，原本單純的討伐行動逐漸揭露出隱藏於國家體制、科技發展甚至時間軸背後的巨大陰謀。唯有完整體驗雙主角劇情，才能拼湊出整個世界的真相，感受層層交織的敘事魅力。

在玩法上，最大的特色在於「念力動作系統」。不僅能使用近戰武器進行流暢的連段攻擊，更可以即時操控場景中的物件——如車輛、鋼筋或大型設備——作為武器砸向敵人，形成華麗且具有破壞力的連擊。戰鬥節奏快速且充滿變化，讓人沉浸於一種兼具策略與操作的爽快體驗之中。

另一項關鍵系統是「SAS（Struggle Arms System）腦部連結」。可以與隊友建立精神連結，暫時借用他們的能力，例如火焰附加、雷電攻擊、瞬間移動、隱形或身體硬化等。透過靈活切換能力與連段組合，戰鬥不再只是單純輸出，而是需要思考敵人特性與戰術搭配。隨著與夥伴關係加深，還能解鎖更強大的協力技能與支援攻擊，進一步提升戰鬥深度。

此外，當角色進入「腦力空間（Brain Field）」時，戰場會轉變為充滿數位符號與超現實幾何構成的異空間，角色能力大幅強化，攻擊速度與範圍顯著提升，帶來極具視覺衝擊力與爽快感的戰鬥高潮。

整體而言，本作在市場上獲得高度評價，被視為近年原創日系動作RPG的代表作之一。其獨特的美術風格、流暢且創新的戰鬥系統，以及雙主角交織出的劇情深度，都讓玩家留下深刻印象。儘管部分玩家認為支線任務略顯重複、過場演出偏向靜態對話形式，但這些並未動搖其核心體驗的優秀表現。

這款作品不僅成功融合傳統JRPG的敘事魅力與現代動作遊戲的操作快感，更透過「腦力」這一核心概念，探討科技進步與人類情感之間的關係。對於喜愛高速戰鬥與劇情探索的玩家而言，《緋紅結繫》無疑是一部不可錯過的佳作。

Developed by BANDAI NAMCO Studios Inc. and published by BANDAI NAMCO Entertainment, SCARLET NEXUS (released in 2021) is a “brainpunk” action RPG that combines high-speed combat, deep storytelling, and a dual-protagonist narrative. It presents a futuristic world where advanced technology and human cognition intersect—yet beneath its progress lies a constant existential threat.

The story is set in the near-future city of New Himuka, where humanity has achieved rapid advancement by unlocking the latent potential of the human brain. Through technological innovation, people can wield extraordinary psychic abilities known as “psionics.” However, this prosperity is overshadowed by the emergence of mysterious creatures called “Others”—alien beings that descend from the sky and feed on human brains, rendering conventional weapons useless against them. To combat this threat, humanity forms the Other Suppression Force (OSF), an elite unit composed entirely of powerful psionic users tasked with defending society.

Players experience the narrative through two protagonists: Yuito Sumeragi, a passionate and justice-driven young man who joins the OSF after being saved as a child, and Kasane Randall, a calm and exceptionally gifted psionic recruited for her natural talent. Although both possess powerful psychokinesis, their perspectives and motivations differ. As their journeys unfold, what begins as routine combat missions gradually evolves into a complex conspiracy involving government secrets, advanced technology, time manipulation, and hidden truths tied to their own pasts. Only by experiencing both storylines can players fully uncover the layered narrative and understand the world’s true nature.

Gameplay centers around the game’s signature “psychokinesis action” system. In addition to fast-paced melee combat, players can manipulate environmental objects—such as vehicles, steel beams, and machinery—and hurl them at enemies. This creates dynamic, visually striking combat sequences that blend weapon attacks with psychic abilities seamlessly, delivering both intensity and strategic depth.

A defining feature is the SAS (Struggle Arms System), which allows the protagonist to link with teammates and temporarily borrow their abilities. These include powers such as pyrokinesis, electrokinesis, teleportation, invisibility, and hardening. By switching abilities in real time and combining them with attack chains, players can adapt to enemy types and develop varied combat strategies. Building stronger bonds with allies further unlocks enhanced combo techniques and support attacks, enriching both gameplay and character relationships.

Another standout element is the “Brain Field,” a special state that transforms the battlefield into a surreal digital-psychedelic space filled with abstract geometry and visual code. In this mode, the player’s abilities are significantly amplified, increasing attack speed and range while delivering a highly stylized and exhilarating combat experience.

Overall, SCARLET NEXUS received strong critical reception and is widely regarded as one of the most impressive original Japanese action RPGs in recent years. Its bold art direction, innovative combat system, and dual-perspective storytelling have been particularly praised. While some critics noted repetitive side missions and a reliance on static, visual-novel-style cutscenes, these minor drawbacks are largely outweighed by the game’s core strengths.

In conclusion, SCARLET NEXUS successfully bridges the gap between traditional JRPG storytelling and modern action gameplay. By centering its design around the concept of “brain power,” it not only delivers thrilling combat but also explores the relationship between technological advancement and human connection, making it a must-play title for fans of action-driven RPGs.
