In the not-so-distant future.
A certain weapon, secretly under development, has finally been completed.
The worst bipedal robot in history, clad in tough armor that can withstand a nuclear attack, and equipped with the threat to annihilate humanity in 7 days.

You are a member of a special forces unit dispatched from a certain country to destroy that robot.
Through years of espionage, you have finally located the factory where the robot is being developed.
Just as you disable the heavy security and break through the factory gate!
Suddenly, the machinery roars to life, and the entire factory begins to operate!

"INITIATING POWER SUPPLY. 60 MINUTES REMAINING UNTIL FINAL WEAPON ACTIVATION."

You all fall into despair at the words displayed on the monitor.
At this rate, the robot will awaken and begin its attack on humanity.
Why on earth!? Did the robot activate?

There is little time left.
Can you use the devices hidden in the factory to solve various mysteries and save humanity?
