At the top of the Black Cyberware hit list are cyberweapons; hidden killing tools that can be buried in your skin until the moment you want to take someone out. Cyberweapons are normally not available on the open market (the only exception are scratchers and vampires), and locating them usually involves going down into the local Combat Zone, finding a Fixer, and paying a lot of euro to ugly, nasty, violent people who would normally consider you spare parts.
Boosters, of course, are drawn to cyberweapons like a 'zoner to zoom dust.
Scratchers: Implanted metal or carbo-glas fingernails. The incredible sharpness of the material makes these as deadly as razor blades (1D6/2 per hand damage). Scratchers cut on the bias, requiring the user to slice crossways, not rip downwards. Most people lacquer their scratchers, making them indistinguishable from normal nails (the enamel has no effect on the sharpness). These are not considered lethal (and therefore black market) cyberwear, and can be purchased in any local clinic.
Vampires: Implanted fangs, usually made up of carbo-glas or superchromed metal. You can have a full set implanted (called the Sharkgrin Special, it causes 1D6/2 in bite damage), or canines only (1D6/3 damage). These are considered to be "decorative," not black market cyberwear, and can be purchased in any local clinic. Vampires can be augmented with poison injectors (which are black cyberware) for double the normal price.
Rippers: Longer, heavier versions of scratchers (1D6+3 per hand damage). The top two joints of each finger are replaced with a plastic and metal sheath, in which three inch carbo-glas claws are housed. The rippers can be extended by clawing the hand in a catlike fashion. Most people wear false fingernails over their rippers, making them much harder to spot (a DIFF task). Rippers are considered a form of black market cybertech and as such is not accessible through the average on-the-Mall clinic. Rippers cut in all directions, and are considered Edged weapons for AP purposes.
Wolvers: The longest and deadliest of the implant blades, wolvers are implanted along the back of the hand. When the hand is clenched in a fist, the thin, triangular blades telescope and lock into place, remaining extended a full foot until the hand is relaxed. Damage is 3D6/hand. Treat as Edged weapons for AP purposes.
BigKnucks: Reinforced knucklebones, giving the fist the impact value of a pair of brass knuckles (1D6+2). This is considered a form of black market cybertech, and as such is not accessible through the average on-the-Mall clinic.
Slice N' Dice: Mono-filament wire spool mounted in end of one finger, with a weighted, false fingernail to give it balance and swing. Monomolecular wire will cut through almost any organic material and most plastics. Can be used as a garrotte, cutter or slicewhip. This is considered a form of black market cybertech, and as such is not accessible through the average on-the-Mall clinic.
Cybersnake: This is a simpler version of the cybersnake found in the Hardwired supplement. This version has far less features and is limited to making a rake attack only. The rake has a range of 1 meter and inflicts 1D6 in damage each time it hits. The cybersnake may be mounted in any body orifice 1" or larger, or may be implanted in the shoulders using a special mount.
