In X-Blades, the player takes on the role of the enchanting heroine Ayumi, who survives a breathtaking dance of blades through the Hordes of Darkness. The long-haired beautiful anime, with her pistol blades and mind-blowing leaps, whirls and swirls from one fantastic level to the next.

In brief: An anime-style, opulent hack ’n' slay spectacle for fans of entertaining action games. X-Blades creates a fantastic universe around the attractive heroine, who has to fend off innumerable monsters and imposing boss opponents with her power and tactics. A long list of all sorts of magic spells widens the range of potential forms of attack. Once Ayumi has collected enough experience points, she can activate new skills. The anime-style level design is what really gives X-Blades its special flair. Around 40 magical indoor and outdoor worlds dazzle in an enthralling rhapsody of color. Action and magical effects are impressively incorporated through the use of cinema stylistics such as bullet time or motion blurring.
