Mark Knights, one of the best commanders at A.S.R.F, has been summoned to participate in the latest project brought up: Mission 12, also known as "Return to the Moon." The A.S.R.F had this mission in mind for over 14 years, and now it was time to turn it from paper to reality. Mark and his crew were set up and trained to go on this fairly simple, yet complex, mission. Everything goes smooth, and no complications rise… until later.
