Kingdom Under Fire: Circle of Doom is an Action RPG game based on the universe of Kingdom Under Fire series. The previous Kingdom Under Fire series were Action RTS titles that recreated realistic fantasy battlefields of massive scale. Circle of Doom focuses on the development of one individual character, and utilizes an easy-to-learn game system and control mechanics. Circle of Doom is filled with never-before-imagined innovation and fresh ideas. Explore randomly generated vast dungeons and face off monsters swarming the screen in thousands and attacking from all directions along the floors, walls, and ceilings of the dungeons. Actively engage in dynamic battle and create effective combos with various weapons to defeat the monsters. During the heated battle, everything in the environment can be destroyed and affect the movement of enemies. Sometimes carving out a hole in the wall may lead to a new path or unearth valuable items. The heroes will find increasingly devastating and spectacular ways to purge the evil in the forms of new abilities and weapons, or even create their own arsenal by combining the existing ones. Circle of Doom also delivers a complex and twisted story plot in a very different and new way. During a multiplayer game, one player's choice to stick with the plot will not slow the others from journeying onward.
