Queen's Gate is a vehicle to bring licensed characters into Queen's Blade's world. Queen's Gate includes some well-known characters and character designers. Like Queen's Blade, it is also licensed from the Lost Worlds system, and completely compatible with any Lost Worlds book. As usual, it is primarily a one-on-one game, in which each player must have a book representing a character. The players swap books, so that each sees how his opponent reacts to his decisions.

The Lost Worlds system uses a much more complex version of rock-paper-scissors, in that both players blindly select an action, hoping to second-guess each other and score a hit.

Part of the Lost Worlds series of books.
