The Dueling MachineCompact Disc, 21 April 2015

Imagine a mechanism that would end all wars and bloodshed. A machine that can create a virtual world where conflicts seem to be fought, but no one dies. Dr. Leo's Dueling Machine is just that. But when a warrior from the Kerak Empire finds a way to circumvent the machine, actually killing his opponents, the results are devastating. His secret knowledge of the machine could lead to actual, not virtual, war. Dr. Leo and his assistant must work quickly to discover what Kerak knows. Their lives, their planet, and the preservation of peace depend on it.
