This article or section contains information from the optional Covert Missions in StarCraft II: Wings of Liberty.
Collection of Jorium
Fighting a war against Mengsk took money, and that didn't grow on trees. Minerals could be found on Redstone III, however, and that's what a contact named Gabriel Tosh wanted harvested. Taking the job, the Raiders carried out a successful mining operation and found themselves financially rejuvenated, along with Tosh as a member. Raynor had his suspicions, but let them pass for the time being, even with the revelation that the minerals collected included jorium, a mind-altering chemical.
Collection of Terrazine
On Bel'Shir, the Raiders encountered the Tal'darim, a band of protoss fanatics protecting terrazine, which they considered to be the "Breath of Creation". It was a gas that Tosh wanted and once again, the Raiders pulled off a successful smash and grab. After the mission, the Raiders received a highly encrypted transmission from a mysterious source claiming that Tosh was a spectre. Tosh didn't deny this, but maintained that the message had been sent by Arcturus Mengsk to divide them. Raynor took him at his word, but also heard that the message ended with "I'll be in touch soon."
"Soon" involved New Folsom Prison, which Tosh wanted assaulted. However, the Raiders found out who had sent the message — a ghost named Nova. She explained that the jorium and terrazine collected were part of Tosh's plan to build a spectre army, and that attacking New Folsom would essentially be releasing psychopaths into the galaxy. Jim Raynor had a choice between assisting Nova or Tosh.
Breakout of New Folsom Prison
Raynor stayed loyal to Tosh, and helped bust open the prison, freeing the spectres along with political prisoners. Tosh and Horner debated what the real victory was, both having different views on the nature of humanity and government. Raynor still believed in Horner's vision of a better future, but knew that men such as Tosh and himself weren't meant for it.
Ghost of a Chance
Raynor decided that Tosh was too dangerous and aided Nova. With Nova's aid, the Raiders destroyed Tosh's jorium stockpiles, terrazine tanks, and his psionic waveform indoctrinator, effectively ending his goal for a spectre army. After the mission, Nova assassinated Tosh.
