”It feels great just moving your favorite characters around. But what if you could enjoy a different playstyle every time you play?” BLAZBLUE ENTROPY EFFECT X is the realization of such greedy fun. Derived from the BLAZBLUE series, this roguelite action game combines beautiful 2D visuals, diverse action, and user-friendly controls. While controlling 14 unique characters familiar to the series, you will take on battles that transcend worlds. Making the most of each character's presence cultivated as a fighting game, while adding the roguelite-unique trial and error of “How should I build them next?”, it cannot be fully appreciated with just a single playthrough. It is a title that people familiar with the series can enjoy as jumping into a new battlefield, and newcomers can enjoy as a stylish 2D action game.

What is interesting about this game is that your battle style is not completely fixed at the moment you choose a character. Each character has unique skills called “Potential,” which allow you to change the way you fight itself through their power. Furthermore, because you can freely combine a wide variety of tactical skills, even the time spent thinking “What happens if I combine this ability with that effect?” becomes part of the strategy. Even with a character you were not used to handling at first, depending on the training and combinations, you might bring out unexpected strength. Rather than simply raising stats to make them stronger, the unique depth of this game lies in building your own setup.

For those who thought, “I went through all the trouble to make them strong, but if I use another character, do I start from scratch?”, we want you to pay attention to the system where you can pass down the abilities of a trained character to another character. Through this, the act of raising one character does not end with that character alone, but leads to possibilities when using a new warrior. By passing down abilities while testing the characteristics of each of the 14 characters, the range of tactics will rapidly expand through the player's own ingenuity. The design where the next challenge naturally arises, such as “This time let’s combine this ability with this character,” is an excellent match with roguelites that are played repeatedly. Every time you clear a run, you can enjoy the feeling of accumulating not only experience, but also new ideas.

Not only the action, but also the story filled with mysteries cannot be missed. The stage is the “Lab,” a dimension where research is being conducted to save a world heading toward destruction. According to the laboratory director, Dr. Mercurius, the key to stopping the collapse of the world is the research of “Possibility,” and for that purpose, “Fragments of Possibility” are required. The fragments lie dormant not in the existing world, but in the “Sea of Possibility” that exists in the gaps between worlds. And the protagonist Ace is the only existence that can dive into it. In other words, the repeated challenges of the player themselves are incorporated into the story as actions to save the world. Since the game system and setting are naturally connected, you will feel a story-related meaning even in the basic gameplay of a roguelite: “trying again.”

However, it does not end with the world-saving research simply progressing smoothly. As Ace repeatedly dives into the “Sea of Possibility” while receiving support from the doctors, an abnormality eventually occurs in his body. Furthermore, mysterious images flow into his brain, and even the intriguing phrase “Power of the Azure” makes an appearance. Why do numerous memories flow into Ace, can the world really be saved, and what is hidden behind the research? Just when you thought you were enjoying exhilarating combat, before you know it, you are heading toward the next dive with a desire to “see what lies ahead.” Such narrative pull is also a major attraction supporting this work.

The charm of BLAZBLUE ENTROPY EFFECT X is not limited to the single point of being able to play a roguelite with BLAZBLUE characters. The 14 characters, variations through Potential, combinations of tactical skills, training via ability inheritance, and the mysterious story revolving around “Possibility.” As each of these overlaps, they create different developments every time you play. “With this combination, I might be able to fight in an even more interesting way.” The moment you think that, the next dive has already begun. Rather than tracing a predetermined correct answer, you find new possibilities by yourself. That trial and error is precisely the real thrill to be fully savored in this work.
