The Omega Missile (Final Gambit)

Created by the U.S. government as a last ditch scenario, The Omega Missile is the code name of an operation to launch every nuclear weapon in the U.S's arsenal in case of a surprise nuclear attack. When a maniacal rogue scientist and his hired gang of expatriates gain control of the Omega Missile, they hold the world hostage. Once the satellite launches, it's only a matter of hours before Armageddon. Enter ex-covert agent Thorpe. The satellite launched, Thorpe has little time to infiltrate the Omega Missile operations center and find a way to end the siege--and the clock is ticking.
