《螺旋》（Rasen）是風格鮮明、極度講求操作技巧與節奏感的競技型動作對戰遊戲，由獨立開發者Abyss Deepen一人製作並發行，預計於2026年在 PC（Steam）平台推出。本作深受Soulsborne系列、《隻狼》以及高速對戰遊戲風格影響，試圖將精準刀劍戰鬥、黑暗氛圍與快節奏競技融合在同一個舞台中，打造以「技術決定一切」為核心的 PvP 與 PvE 競技場體驗。

在世界觀上，描繪的是一個陷入「無盡死亡循環」的世界。這裡不存在真正的終點，只有一次又一次的戰鬥、倒下與再度站起。主角是在混亂中遊走的致命流浪者，他們在這片扭曲的世界裡，以刀鋒與意志證明自身的存在。雖然本作並非以大量文本敘事為主，但透過場景氛圍、角色設計與不斷重複卻逐漸升高的戰鬥強度，營造出一種壓迫、孤獨又近乎儀式性的死亡循環感，讓戰鬥本身成為故事的一部分。

操作與戰鬥系統是絕對核心。並不鼓勵無腦輸出，而是要求玩家對每一次出手與防禦負責。防禦手段並非單一按鍵解決，而是包含精準格擋、阻擋、閃避與側身移動，必須根據敵人的攻擊節奏與距離選擇正確反應。一次成功的格擋不僅能避免傷害，還可能創造反擊窗口，將劣勢瞬間轉為主動。

進攻同樣建立在節奏與時機之上。攻擊必須精準計算距離與出手時機，並透過技能銜接來突破對手防禦。盲目揮刀只會讓自己暴露在破綻之中，真正的關鍵在於「讀懂對手」。需要觀察敵人的行為模式，利用假動作引誘對方出手，或刻意保留攻擊來製造心理壓力，逐步掌控整個交鋒的節奏。戰鬥因此呈現出高度博弈性，宛如一場高速進行的心理戰。

當戰鬥進入白熱化階段，還能啟動「野獸模式」。這是一種進入極度專注狀態的強化系統，能暫時提升角色能力並解鎖更具破壞力的致命招式。野獸模式不只是單純的強化爆發，而是一種風險與回報並存的選擇，若使用時機不當，反而可能成為對手反擊的破口。

在模式方面，同時支援PvP與PvE。可以與朋友組隊，挑戰其他玩家，或單獨面對具備高侵略性與戰術思考能力的AI對手。對戰模式涵蓋決鬥、衝突、大規模死亡競賽等，從一對一的緊張劍鬥，到多名敵人同時壓迫的混戰局面，都要求玩家在高速判斷中結合技巧與策略。特別是在面對壓倒性敵人數量時，走位、節奏控制與目標選擇將成為生存關鍵。

整體而言，《螺旋》（Rasen）是明確為硬派動作玩家打造的作品。它不試圖取悅所有人，而是專注於提供深度極高、回饋感強烈的戰鬥體驗。對於喜愛《隻狼》式精準格擋、黑暗幻想氛圍，以及講求操作與對戰技術的玩家來說，《螺旋》是一款能讓人不斷磨練自身、在失敗與突破中獲得成就感的獨立佳作。

Rasen is a stylish, skill-driven arena combat game developed and published by solo indie developer Abyss Deepen, scheduled for release on PC (Steam) in 2026. Strongly influenced by the Soulsborne series, Sekiro, and high-speed competitive action games, Rasen blends precise blade combat, dark atmospheric world-building, and fast-paced PvP/PvE encounters into a game where player skill and timing define everything.

The world of Rasen is trapped in an endless spiral of death. There is no true end—only repeated cycles of combat, collapse, and rebirth. Players take on the role of deadly vagabonds wandering through chaos, proving their existence through steel and will alone. Rather than relying on heavy exposition, the game conveys its narrative through oppressive environments, character designs, and the escalating intensity of combat itself. The act of fighting becomes the story, reinforcing themes of inevitability, isolation, and survival within a broken world.

Combat and controls are the absolute core of Rasen’s design. The game rejects mindless button-mashing and instead demands full accountability for every action. Defense is multi-layered and deliberate, involving precise parries, blocks, dodges, and sidesteps. Players must read enemy attack patterns, distance, and rhythm to choose the correct response. A perfectly timed deflection not only negates damage but can also open a window for a decisive counterattack, instantly shifting momentum.

Offense is equally dependent on timing and awareness. Attacks must be carefully measured, with abilities chained together to break through an opponent’s guard. Reckless aggression is heavily punished; true mastery comes from reading the opponent. Players are encouraged to use feints, hesitation, and baiting tactics to manipulate enemy behavior, turning each duel into a high-speed psychological battle. Every exchange feels like a contest of intent rather than raw numbers.

As battles intensify, players can activate Beast Mode, a heightened state of lethal focus that enhances abilities and unlocks devastating techniques. This mode is not a simple power boost—it is a calculated risk. Poor timing or overcommitment can leave players dangerously exposed, making its use a strategic decision rather than a guaranteed advantage.

Rasen supports both PvP and PvE play. Players can team up with friends, challenge other players, or face highly aggressive and tactically aware AI opponents. Game modes range from tense one-on-one duels to chaotic clashes and large-scale deathmatches. In encounters where players face overwhelming numbers, survival depends on positioning, target prioritization, and rhythm control as much as raw execution.

Overall, Rasen is unapologetically designed for hardcore action players. It does not aim to please everyone; instead, it focuses on delivering a deeply rewarding combat system where improvement comes through discipline, failure, and mastery. For players who appreciate Sekiro-style precision, dark fantasy atmospheres, and competitive, skill-based combat, Rasen offers a demanding yet immensely satisfying indie experience where every victory is earned.
