Limited edition comes with a setting guide, 2-disc soundtrack CD, and an acrylic key chain featuring Kirika and Masha. [Machine Translation] Demon castle action, reborn here. --It's time for revenge, Demon Lord! (What is "Grim Guardians: Servant of the Dark"?) This is the latest title in the "Grim Guardians" series of 2D side-scrolling action games in which players battle demons. In this long-awaited evolution from the stage-clearing type to the exploration type, players explore the demon world, strengthen their weapons, and fight against the boss demon kings who rule each region, all while using two different characters, Kirika and Masha, with different abilities. All for the sake of the restoration of "Maxim the Demon King", the "Demon Lord" whom you serve. The enemies are demons, the allies are demons, and even a demon hunter from the human world joins in the battle, making for a crazy adventure. (Story) Demons are constantly fighting each other in the demon world. The most powerful demons are called "demon kings," and the demon kings fight for supremacy over the demon world day and night. One day, the "Demon King Maxim," whom the main characters "Kirika" and "Masha" serve as maids, has his castle destroyed by the rival demon king "Raisenog. While all the vassals are killed, Kirika and Masha survive. And Maxim, the demon king who survived but whose appearance has changed drastically. The story of revenge and resurrection of the three begins! Explore the vast demon world and revive the Demon Lord and his friends! While maintaining the action that made the previous title "Grim Guardians: Demon Purge" so well-received, the game has been expanded to include more exploration and collecting activities! The map has been expanded from a stage-clearing type to an exploration type, or "Metroidvania," and is more than twice the size of the previous title. The demon world is littered with hidden passages and gimmicks to solve, and is a barrier to the goal of collecting the bones of "Maxim the Demon King" - the "Master of Demons" - and resurrecting him. Depending on the situation of the main characters, Kirika and Masha, and the sub-weapons they possess, different routes and strategies can be tried and tested in order to achieve the goal! In addition, you can expand and add support functions to the Demon King's Castle by finding and resurrecting the Demon King's vassals who have become souls and scattered throughout the Demon World. Fully-voiced conversations with the unique vassal demons will be developed to add color to your playtime. / Demonic action to switch between sisters! The new control characters are the demon maid sisters, Kirika, who excels at long-range attacks, and Masha, who excels at melee attacks! The sisters also have different sub-weapons that can be used by consuming magic power, so switch control characters at the appropriate time to cover each other's weaknesses. Even if one of the sisters runs out of power in a battle against demons, you can revive her by using "Sister Rescue" when you get to her. The game also supports 2-player local play and 2-player online co-op, so you can enjoy exploration action with sisters from all over the world! (*Two player online co-op play will be supported in an update. / A substantial collection element! Consumable items, sub-weapons, and passive expansion items (magical treasures) will randomly drop from treasure chests and hostile demons. By acquiring these items, new actions characteristic of the sisters will become possible, and players will be able to enjoy further strategies and new elements of route exploration. In addition, you can customize sub-weapons by combining them with each other, so items you no longer need will not go to waste. Collect, synthesize, and enhance items until you are satisfied! Play with a "style" that suits you! As in the previous title, there are three "styles" available: Casual, Experienced, and Challenger, so you can choose the one that suits you best. You can change "styles" as many times as you like during the game, and there is no difference in the storyline and other content, and no disadvantages. Choose the "style" that best suits your mood and what you want to play! (CERO age rating: to be determined)
