An Anti-Shock Implant, also known as an A-S Implant, is a small device that can be implanted in the back of a character's neck, making the character immune to stun attacks. A-S implants must be installed at a hospital. An A-S Implant costs 2,000 Cr, including installation. A robot may be equipped with a surge protector that is functionally identical to an A-S Implant. The cost of this device is 2,200.
