When Joanna agrees to join the Carrington Institute to stop dataDyne, Carrington explains that Zeigler had been working on an algorithm capable of decoding extraterrestrial glyphs at a dig site in South America. Traveling to Peru, Joanna learns that the glyphs are leading dataDyne to search for an ancient artefact which acts as a power source for the Graal, a device which endows individuals with superhuman powers. Joanna plants a tracking device on the artefact before sneaking aboard a dataDyne dropship. The dropship takes her to Africa, where Zhang Li has located the Graal buried under the African sands. As the Carrington Institute starts an offensive on dataDyne, Joanna rescues several Carrington Institute agents before avenging her father's death by killing Mai Hem. She then infiltrates an arena and faces off against Zhang Li, who dispatches Chandra after using the Graal. After Joanna defeats Zhang Li in a final battle, Carrington commends her efforts, saying she did "Perfect".
