About the Game

White Cat Project NEW WORLD'S marks a significant turning point for Colopl Rune Story, rebuilding the experience from the ground up with a focus on more dynamic combat, deeper character systems, and a richer ongoing story. The game is set on a mysterious continent suspended in the sky, where the chance encounter between a white cat and a black cat sparks a grand adventure that unfolds across generations. What begins as a seemingly simple tale gradually expands into an epic spanning characters, conflicts, and a world full of secrets waiting to be uncovered.
At the heart of this update is the introduction of the Grand Class, a new tier of character progression that fundamentally changes how players approach combat. Grand Class characters come equipped with powerful special moves that can be executed through intuitive, simplified controls, removing barriers that might slow down the action. Paired with this is the Break Attack mechanic, a new combat action specifically designed to deal enormous damage when used correctly. Knowing when to trigger a Break Attack and how to set it up within a fight adds a tactical dimension that rewards players who pay attention to enemy patterns and battle rhythm.
The Skill Combination system is where much of the new strategic depth lives. Rather than controlling a single character at a time, players build a formation from their assembled roster, and during battle, these characters enter the field in sequence to fire off their skills together. The combinations that emerge depend entirely on which characters are in the formation and the order in which their skills are activated. This creates a near-endless variety of approaches, encouraging experimentation across different team builds:
Mix characters from different classes to create unexpected synergies
Adjust activation order to chain skills for maximum effect
Revisit older characters with new formations to discover fresh combinations
Adapt strategies for different enemy types and boss encounters
Movement, basic attacks, and skill usage are all handled through one-handed controls, keeping the action fast and fluid without requiring complicated inputs. The game's world is open enough to reward exploration, and the combat itself is designed to feel visually exciting, with flashy animations and impactful effects accompanying most major actions.
For players who enjoy cooperative play, White Cat Project NEW WORLD'S supports group battles with up to four participants. These sessions let friends bring their individually trained characters into shared encounters, making the results of personal progression feel meaningful in a social context. The training systems available for customization are extensive. Players can modify weapons to suit specific playstyles, equip accessories that provide strategic bonuses, utilize tablets as part of a broader gear system, and invest time in building and developing their in-game town. These systems layer on top of each other to give dedicated players a long runway of meaningful progression.
The narrative side of the game receives consistent attention as well. Event scenarios are added on a monthly basis, each one fully voice-acted and featuring a cast that includes notable performers such as Yuki Kaji and Yui Horie. The writing introduces a wide variety of characters, each with distinct personalities, and the regular updates ensure there is always new story content to engage with. For players who invest in the characters themselves, these scenarios add meaningful context and personality to the roster beyond their battle roles.
