This article is about a subject from outside Hideo Kojima's core "Metal Gear Saga." It has some level of canonicity within the continuity, but reader discretion is advised.[?]

Repair Units were an integral part of cyborgs by the late 2010s. As their name suggested, they proceeded to aid in the repair of various damages to cyborgs.

Behind the scenes

Repair Units are a collectable recovery item in Metal Gear Rising: Revengeance. Sharing a similar role to rations in previous Metal Gear games, they allow the player to restore the life and fuel cell gauges upon being collected, although to a far lesser degree to the Repair Nanopaste and Electrolyte Pack.
