There is a war raging in silence. Mechanical gods are the foot soldiers for warring factions of beings beyond our solar system, beyond our comprehension. Here among the pyramids, sphinxes, marketplaces, and tombs, they are visible only to animals without souls. Alien beings pilot robots in this bizarre arena to determine the victor in an epic struggle. They seek the very souls of the ancients. Followers of Osiris have been driven to madness by an unquenchable thirst for power. Their sole objective is to control mindless slaves devoted to sacrifice and the building of magnificent monuments. Their enemy is reason and freedom, the powers of Ra. You must lead the forces of Ra against the wave of madness. Face the challenge of capturing the cities and freeing the souls of the inhabitants.
