From the introduction: Planet Earth, year 20XX. After the great global pandemic, the world slowly began to recover. User summary: Characters in the game are enhanced human members of the Zombie Extermination Task Force. New Z.E.T.F. males receive enhancement shots in the stomach; new Z.E.T.F. females receive enhancement shots in the breast. Z.E.T.F. members also are subjected to forced reproduction programs; the most-fecund females are classified as Mother o' Mares and held in "dark chambers not two floors below street level". Z.E.T.F. members not selected for forced reproduction enter a program of training and brainwashing which results in about an 80% morality rate. The lucky (?) few who survive become active agents. Characters in the game are defined by four Attributes (Focus, Vigor, Dexterity, Agility) and their type of gear (Sneaking, Assault, Armored). Characters also have an assigned primary and secondary weapon.
