Returning from Triton, Jack learns that Troy has been killed in action on Mars while attempting to locate a mysterious psionic orb.

Jack is sent to Antarctica to wipe out the test subjects recovered from the Triton incident that got loose and stole a batch of Cyclone weapons.

After this, Jack is sent to Jupiter's moon Io, retaking the colony from Jovian gangsters who commandeered a sulfate mine and production plant.

She explains that President Krieger used Jack to locate and bring back the psionic orb and the Triton alien soldiers' genetic databank, because this will give him all but unlimited psionic power and a private military company staffed with physically superior extraterrestrial soldiers.

Eve is the head of the rebel faction the Alliance Of Democracy, which is attempting to overthrow Krieger's presidency and replace it with their own regime.

Jack takes on Krieger's private army as he infiltrates the president's headquarters, but he is captured by a teleporter in his office and restrained to a chair.

Krieger uses his Extractor torture device to try to retrieve the Terrablast implant from Jack's skull while putting him under an induced hallucinatory nightmare to erode his will.
