【Gravity Wave Corporation Security Guard Training Manual】
Welcome to Gravity Wave Corporation, our future guardian of the gate.
Read every word of this manual carefully and make sure you understand it. Your duties go far beyond checking employee badges. The company's security depends on your vigilance.
Your Primary Duties
1. Identity Verification
You will be stationed at the company's only entrance. Every individual attempting to enter Gravity Wave Corporation must pass your inspection. Examine every detail of their documentation and use the telephone to verify their identity. In this job, your most important weapon is your judgment.
2. Admission and Elimination
If you are certain that a visitor is human and their intentions are legitimate, grant them entry and wish them a pleasant day at work.
If you notice anything unusual, however slight, you are authorized—and required—to press the “Alarm” button immediately and report the threat level to headquarters. Headquarters' cleanup system will take care of the rest.
