Attention Special Agent 4125: Elvin Atombender Back in Power!
It has been two short years since Elvin Atombender was vanquished. Your supreme efforts, 4125, helped prevent global domination and anarchy. But now, like a phoenix from the ashes, Elvin has rised once again. Reports from the country indicate that Elvin has established a new stronghold, the headquarters of which is a five tower complex.
Early reports indicate the presence of guards, robots, mines and trap doors. Only one person has the vital ability to negotiate the maze of elevators; and the strength to outwit Elvin himself. So once again we must ask you to make the supreme sacrifice. We are aware that it is a mission from which there may be no return, but we have to put our trust in you, if global destruction is not to result.
Your mission starts today.
We wish you good luck and God's speed.
I.M.A. Special Terrorist Unit.
