The plot is linear[4] and is mostly provided for the introductory and concluding full-motion video cutscenes. After the "Material Defender" (voiced by George DelHoyo)[40] has destroyed all of the Solar System's mines in the original Descent, he stops in the asteroid belt to dock. He is then contacted by Post-Terran Mining Corporation executive Dravis, who exploits a loophole in a contract to coerce him to accept a new mission or forfeit his reward and face legal action. The Material Defender consents, and as Dravis tries to convince him that he is merely embarking on a reconnaissance mission, his ship is fitted with a prototype warp core. He is then sent to clear out PTMC's deep space mines beyond the Solar System.[12][41]
