《賞金姊妹花》（Bounty Sisters，バウンティシスターズ）是結合動作射擊與冒險元素的橫向卷軸遊戲，帶有濃厚的街機風格與美式漫畫氛圍。由Pixel開發，於2025年12月在Switch/Steam販售，最多三人遊玩。

故事背景設定在一個結合西部荒野與未來科技的架空世界，跟隨兩位性格迥異、身手不凡的姊妹駕駛三台不同特色的機器展開冒險。她們是聞名於世的賞金獵人，專門接受高風險任務，追捕惡名昭彰的罪犯，換取鉅額賞金。

劇情部分圍繞著一場牽涉龐大陰謀的追捕行動展開。姊妹原本只是為接下一單高價懸賞，但隨著調查深入，她們逐漸發現這名通緝犯背後隱藏著威脅整個大陸的秘密勢力。透過關卡間的過場動畫與角色對話，展現姊妹之間的互動與默契，以及面對危險時的不同處事風格——姐姐冷靜沉著、擅長精準狙擊，妹妹則衝動火爆、偏好近距離爆發攻擊。這種人物性格差異也影響戰鬥策略與遊戲體驗。

操作方面，採用經典的2D橫向射擊玩法，自由切換操控姊妹，或者在雙人合作模式下與朋友各自操縱一名角色，協同作戰。角色擁有各自獨特的武器與技能，例如姐姐可使用長程步槍與高精度瞄準，妹妹則配備散彈槍與近戰衝擊技能。關卡設計多樣，涵蓋城鎮槍戰、火車追擊、荒野決鬥以及科技基地突襲等場景，每關還會出現不同的Boss戰，需要靈活運用閃避、反擊與地形掩護來應對。遊戲的射擊手感爽快，節奏明快，並支持道具收集與武器升級系統，在推進劇情的同時強化角色能力。

市場反應方面，在Switch平台推出後獲得不少動作遊戲愛好者的關注。玩家普遍稱讚其美術風格鮮明、操作流暢，以及雙角色設計帶來的多樣戰鬥策略。特別是在雙人合作模式中，姊妹技能互補的玩法被認為是遊戲的亮點之一。不過，也有評論指出遊戲流程偏短，部分關卡難度在單人模式下挑戰性不足，可能導致耐玩度略顯有限。但作為節奏輕快、充滿街機感的動作射擊小品，《賞金姊妹花》依舊獲得正面評價，尤其適合喜愛合作射擊與快節奏戰鬥的玩家。

"Bounty Sisters" (バウンティシスターズ) is a side-scrolling game that blends action shooting and adventure elements, infused with a strong arcade feel and the visual flair of American comic books. Developed by Pixel, it is set to release in December 2025 on Switch and Steam, supporting up to three players.

The story takes place in an alternate world combining Wild West deserts with futuristic technology. Players follow two highly skilled, contrasting sisters piloting three uniquely designed machines as they embark on daring missions. As world-renowned bounty hunters, the sisters specialize in high-risk contracts, tracking down notorious criminals for massive rewards.

The plot centers on a high-stakes manhunt that gradually unravels into a continent-spanning conspiracy. Initially, the sisters take on a lucrative bounty, but their investigation reveals that the target is tied to a shadowy organization threatening the entire continent. Through animated cutscenes and in-game dialogues, the game showcases the sisters’ personalities and teamwork — the elder sister is calm, precise, and a master sniper, while the younger sister is impulsive, hot-headed, and excels at close-range explosive combat. These personality traits influence not only the narrative but also the gameplay strategies.

Gameplay adopts the classic 2D side-scrolling shooting style, allowing players to freely switch between the sisters in single-player mode or team up in co-op, each controlling one character. Every character has distinct weapons and abilities: the elder sister wields a long-range rifle with pinpoint accuracy, while the younger sister uses a shotgun and powerful melee strikes. Stages vary from town shootouts and train chases to desert duels and high-tech base assaults, each capped with unique boss battles that demand skillful dodging, counterattacks, and use of environmental cover. The shooting mechanics are fast-paced and satisfying, with item collection and weapon upgrade systems that enhance the sisters’ abilities as the story progresses.

In terms of market reception, the Switch version has drawn attention from action game enthusiasts. Players praise the bold visual style, smooth controls, and the dual-character dynamic that offers varied combat strategies. The co-op mode, in particular, has been highlighted as a standout feature due to the complementary nature of the sisters’ skills. On the downside, some critics note that the campaign is relatively short and certain levels lack challenge in single-player mode, which could impact long-term replayability. Still, as a brisk, arcade-like shooting experience, Bounty Sisters has garnered generally positive reviews, especially among fans of cooperative shooters and fast-paced combat.
