You were a poor mechanic who infiltrated the abandoned Shadow Moses military base. You wanted to find weapons or equipment that you could sell or take apart. Walking around the base and sometimes collecting valuable or useful things, you came across a hangar. You entered it and a huge walker appeared to your eyes. It was disabled. Curiosity got the better of you and you decided to get into the cockpit. After checking the logbook, you saw a report saying that the missile guidance systems had evolved and developed into AI. You accidentally touched the start button and the machine was activated.
The cockpit closed and you were strapped in, which prevented you from escaping. A camera pointed at you and an image of a pink heart appeared on the control panel.
