There has been a second war in Heaven, and a group of rebellious angels has descended to Earth to destroy humankind. These angels, known as the Fallen, are jealous of the mortals' preferred place in the universe. You play Malachi, a loyal angel who must take on mortal form and stop the fallen angels. Malachi's adventures take him from the depths of Hell, to war-torn cities, to the vastness of uncharted space. As Malachi progresses, he learns more of the Fallen's plans. This is a 3D first-person shooter, but it is not just an aim-and-shoot type of game, since the plot is integrated into the game. You'll have to speak and interact with a number of third-party characters to gain information, acquire needed items, or get past certain obstacles. This demo contains three different difficulty levels, in which you must infiltrate the city's power plant to rendevous with an ally.
