白貓 Project（日文：白猫プロジェクト，英文版曾名為 Colopl Rune Story）是日本遊戲公司 Colopl 開發與營運的 3D 動作 RPG 手機遊戲，最早於 2014 年在日本推出，之後推出台港版與全球英文版。它最大的特色是把傳統 RPG 的角色養成、抽卡、多人合作，結合真正即時操作的動作戰鬥，而不是單純看角色自動攻擊。

遊戲名稱中的「白貓」來自作品中的重要象徵角色與世界觀設定。玩家在遊戲中扮演冒險者，踏上尋找神秘「符文（Rune）」力量的旅程，探索漂浮島嶼與各種幻想世界。劇情核心圍繞主角與夥伴們尋找遠古力量，對抗威脅世界的敵人。故事採用日式 RPG 常見的王道冒險風格，有友情、羈絆、魔法與英雄成長元素。全球版《Colopl Rune Story》曾介紹玩家從漂浮島 Astora 出發，追尋失落符文與世界秘密。

在操作方面，《白貓 Project》最大的創新就是「單手操作」。玩家只需要用手指控制角色移動、攻擊、閃避以及釋放技能，不需要傳統虛擬搖桿加大量按鍵，因此非常適合手機遊玩。戰鬥不是回合制，而是即時動作模式，玩家需要躲避敵人攻擊、抓準時機連擊、使用技能擊敗 Boss。這也是當年它在眾多手機 RPG 中脫穎而出的原因之一。

角色系統是遊戲的重要核心。玩家可以收集大量角色，每個角色都有不同職業與戰鬥方式，例如劍士、槍兵、戰士、拳鬥家、弓箭手、魔法師等。不同職業在攻擊距離、防禦能力、技能特色上都有差異，玩家需要依照關卡與敵人特性組隊。除了角色培養之外，武器強化、城鎮建設、資源管理也是遊戲內容的一部分。

遊戲還加入多人合作模式，玩家可以與其他玩家組隊挑戰 Boss 或完成任務。城鎮系統則讓玩家像經營自己的冒險基地一樣，建造設施、提升角色能力，形成「動作 RPG + 城市養成」的玩法。

市場評價方面，《白貓 Project》在日本推出後曾經非常成功，被視為 2010 年代手機動作 RPG 的代表作品之一。玩家喜歡它的原因包括流暢的戰鬥、可愛的日系 3D 美術、角色數量龐大，以及不像許多手機 RPG 只是點擊放技能，而是真正需要操作。

不過遊戲也有一些爭議。部分玩家認為後期角色強度膨脹嚴重，新角色更新速度快，導致舊角色容易被淘汰；抽卡與養成系統也讓部分玩家覺得需要投入大量時間或金錢。另外英文全球版《Colopl Rune Story》雖然受到期待，但營運時間較短，最後停止服務，使不少海外玩家感到可惜。

整體來說，《白貓 Project》是一款在手機遊戲歷史上具有代表性的作品，它把「主機式動作 RPG 操作感」帶入手機平台。雖然後期受到營運與平衡問題影響，但它的單手操作戰鬥、角色養成與即時合作玩法，仍然影響了後來許多手機動作 RPG 的設計方向。

White Cat Project（白猫プロジェクト / Colopl Rune Story）Mobile Game Introduction

White Cat Project (Japanese: 白猫プロジェクト, English version: Colopl Rune Story) is a 3D action RPG mobile game developed and published by the Japanese game company Colopl. It was first released in Japan in 2014 and later expanded to other regions, including Taiwan, Hong Kong, and an international English version. The game became well known for combining traditional RPG elements such as character collection, progression, and multiplayer content with real-time action combat designed specifically for smartphones.

The story of White Cat Project takes place in a fantasy world filled with floating islands, ancient powers, and mysterious runes. Players take the role of an adventurer who travels with a group of companions to uncover the secrets behind the Rune energy and protect the world from various threats. The storyline follows the style of classic Japanese fantasy RPGs, featuring themes such as friendship, adventure, courage, and the growth of heroes. The global version, Colopl Rune Story, introduced players to the floating island world of Astora, where they explored different regions and searched for the lost power of runes.

The biggest feature of the game is its unique one-handed touch control system. Unlike many mobile RPGs that rely on automatic battles or menu-based commands, White Cat Project allows players to directly control their characters by tapping and swiping on the screen. Players can move, attack enemies, dodge attacks, and activate special skills in real time. This action-based system gave the game a more console-like feeling and became one of the main reasons for its popularity.

The combat system focuses on fast-paced action. Players must learn enemy patterns, avoid powerful attacks, and choose the right timing to use character abilities. The game includes multiple character classes, such as swordsmen, warriors, fighters, archers, and magic users. Each character has different attack styles, strengths, and skills, allowing players to create different team combinations depending on the situation.

Character collection and development are major parts of the gameplay. Players can obtain many different heroes through the gacha system, upgrade their abilities, strengthen weapons, and improve equipment. The game also includes a town-building system where players develop their own base, construct facilities, and increase their characters’ overall power. This combines action RPG gameplay with management and progression elements.

White Cat Project also features cooperative multiplayer modes, allowing players to team up with others to challenge powerful enemies and complete difficult missions. The combination of real-time combat, character growth, and online cooperation helped it stand out among mobile RPGs during the 2010s.

In terms of market reception, White Cat Project was considered one of Japan’s most successful mobile action RPGs after its release. Players praised its smooth combat, colorful 3D anime-style graphics, large character roster, and the fact that battles required actual player skill rather than simply waiting for automatic attacks. It was often recognized as a title that pushed mobile games closer to the experience of traditional action RPGs.

However, the game also received criticism over time. Some players felt that character power inflation became a major issue, with newly released characters often becoming much stronger than older ones. This caused previous characters to lose value quickly. The gacha system and heavy upgrade requirements also led some players to criticize the amount of time or money needed to keep up with the latest content. The international English version, Colopl Rune Story, was also discontinued after a relatively short period, disappointing many overseas fans.

Overall, White Cat Project remains an important title in mobile gaming history. Its innovative one-handed action controls, real-time combat, character collection, and cooperative gameplay helped define a new style of smartphone RPG. Although it faced challenges with long-term balance and global operation, its influence can still be seen in many modern mobile action RPGs.
