The game opens with President Krieger of Earth's United Nations talking about how he came up through the ranks of the LightStormer Corps. This turns out to be a recruiting commercial airing at the LightStormer Corps Headquarters. There, Jack Curtis, a new recruit, is talking to his elder brother and commanding officer Blake Curtis. Jack is sent on a training mission, after which he and his fellow LightStormer Troy Alexander receive psionic implants. Troy and Jack are sent on another training mission, through an "abandoned" chemical factory.
