Replacements are prosthetic or artificial units intended to replace lost limbs and damaged organs. Common replacements provide no benefits other than duplicating the essential functions of their biological counterparts, and they present little strain on the beneficiary's overall well-being. In appearance, a cybernetic replacement can be recognizably artificial or virtually indistinguishable from the real thing.

Some replacements of higher PL are built to counter certain drawbacks, as noted. They don't add measurably to the recipient's weight. Cybernetic replacements do not take up implant slots.

If a player agrees to create a 1st-level hero with a prosthetic limb or artificial organ that provides no inherent benefits, the GM may (at his or her discretion) reward that character with an extra action point per level.

Each replacement description includes the following information:

• Benefit: What the cybernetic replacement allows its recipient to do.
• Type: Replacements can be external or internal. External replacements are subject to sunder attacks; internal replacements are not.
• Hardness/Hit Points: The hardness and hit points of the replacement. Internal replacements don't have hardness.
• Base Purchase DC: The purchase DC of the replacement (or the components to build it), at its specified Progress Level. Cybernetic attachments are cheaper to buy at higher Progress Levels; for each raised step in Progress Level, reduce the purchase DC by 2.
• Restriction: The level of license required to purchase the replacement legally, and an appropriate black market purchase DC modifier.

A peg leg is a simple crutch attached in place of a missing foot or calf. The prosthetic begins anyplace at or below the knee.

• Benefit: A peg leg partially replaces the function of its biological counterpart. It allows only limited speed, reducing the recipient's base land speed by 5 feet (as opposed to the more serious speed restriction imposed by having no leg). The recipient takes a -2 penalty on any skill check involving his legs (including Balance, Climb and Tumble), and can run at only his base speed x3.
• Type: External.
• Hardness/Hit Points: 3/10.
• Base Purchase DC: 11.
• Restriction: None.

A hook is a simple melee weapon attached in place of a missing hand or forearm. The prosthetic begins at the elbow or wrist.

• Benefit: A hook partially replaces the function of its biological counterpart. It allows limited manipulation, and any action that r-quires two hands is done at a -4 penalty. A hook can be treated as a simple weapon in an external weapon mount.
• Type: External.
• Hardness/Hit Points: 4/3.
• Base Purchase DC: 12.
• Restriction: None.

An artificial organ fully replaces a defective or destroyed biological organ, such as a heart, lung, eye, or ear.

• Benefit: The artificial organ duplicates the function of its biological counterpart. It provides no special game benefits.
• Type: Internal.
• Hardness/Hit Points: -/2.
• Base Purchase DC: 19.
• Restriction: None.

A prosthetic arm fully replaces a lost or destroyed biological arm. The prosthetic arm may begin at the shoulder, elbow, or wrist. Also available as wetware.

• Benefit: The prosthetic arm duplicates the function of its biological counterpart. It provides no special game benefits.
• Type: External.
• Hardness/Hit Points: 3/5.
• Base Purchase DC: 17.
• Restriction: None.

A prosthetic leg fully replaces a lost or destroyed biological leg. The prosthetic leg may begin at the thigh, knee, or ankle. Also available as wetware.

• Benefit: The prosthetic leg duplicates the function of its biological counterpart. It provides no special game benefits.
• Type: External.
• Hardness/Hit Points: 3/7.
• Base Purchase DC: 17.
• Restriction: None.

This upgraded version of the PL 5 artificial organ not only replaces a defective or destroyed biological organ but is also more resilient than its technological predecessor. Also available as wetware.

• Benefit: The artificial organ upgrade duplicates the function of its biological counterpart and cannot be disabled if the recipient takes massive damage.
• Type: Internal.
• Hardness/Hit Points: -/4.
• Base Purchase DC: 21.
• Restriction: None.

This upgraded version of the PL 5 prosthetic arm not only replaces a lost or destroyed arm but is also more resilient than its technological predecessor. Also available as wetware.

• Benefit: The prosthetic arm upgrade duplicates the function of its biological counterpart but has a greater hardness and more hit points than the basic PL 5 prosthesis.
• Type: External.
• Hardness/Hit Points: 5/10.
• Base Purchase DC: 19.
• Restriction: None.

This upgraded version of the PL 5 prosthetic leg not only replaces a lost or destroyed leg but is also more resilient than its technological predecessor. Also available as wetware.

• Benefit: The prosthetic leg upgrade duplicates the function of its biological counterpart but has a greater hardness and more hit points than the basic PL 5 prosthesis.
• Type: External.
• Hardness/Hit Points: 5/15.
• Base Purchase DC: 19.
• Restriction: None.

This advanced version of the PL 5 artificial organ and PL 6 upgrade not only replaces a defective or destroyed biological organ but is also more resilient and less impairing than its technological predecessors. Also available as wetware.

• Benefit: The advanced artificial organ duplicates the function of its biological counterpart and cannot be disabled if the recipient takes massive damage. In addition, the advanced organ does not count toward the total number of cybernetic attachments the recipient can have before taking negative levels.
• Type: Internal.
• Hardness/Hit Points: -/4.
• Base Purchase DC: 24.
• Restriction: None.

This upgraded version of the PL 5 prosthetic arm and PL 6 upgrade not only replaces a lost or destroyed arm but is also more resilient and less impairing than its technological predecessors.

• Benefit: The advanced prosthesis duplicates the function of its biological counterpart. In addition, this advanced prosthesis does not count toward the total number of cybernetic attachments the recipient can have before taking negative levels.
• Type: External.
• Hardness/Hit Points: 5/10.
• Base Purchase DC: 22.
• Restriction: None.

This upgraded version of the PL 5 prosthetic leg and PL 6 upgrade not only replaces a lost or destroyed leg but is also more resilient and less impairing than its technological predecessors.

• Benefit: The advanced prosthesis duplicates the function of its biological counterpart. In addition, this advanced prosthesis does not count toward the total number of cybernetic attachments the recipient can have before taking negative levels.
• Type: External.
• Hardness/Hit Points: 5/15.
