Velocity 2X: Critical Mass Edition casts players as Lt. Kai Tana, the pilot of the prototype Quarp Jet. Nefarious tactics send Kai Tana and her teleporting Quarp Jet to a galaxy ruled by the evil Vokh, a tyrannical race of aliens who believe they have a divine right to rule the universe. They've created an armada by enslaving other races and seek to make humanity their next conquest.
