NanoTech

NanoTech (or nanotechnology) is a substance using reproduction or reinforcement nanobots to heal or repair damaged surfaces. For Ratchet and Clank their is a Nanotech meter showing how much damage you can take unitl Ratchet or Clank passes.

An experience meter (exp) is located below the NanoTech meter to show how much damage you have to do until your NanoTech count upgrades. When NanoTech upgrades a flashing light appears destroying enemies.

NanoTech is not just for health, but as technology upgrades and advances, it is used to make more powerful devices.

A more advanced substance called ZeptoTech was invented by the Zoni.

Locations
NanoTech is located in NanoTech Crates stacked neatly with other Crates or found as a single unit.

Form
NanoTech is contained in what's called a Nano-orb (nanorb), which has several elements of nanobots (or nanodrone) spinning in fury until a living substance or nano-tech heeding device is detected, then the nanobots break loose and return to the initial object.

Health
NanoTech is used as health. When Ratchet or Clank takes damage, nanotech can repair any blemishes.

Weaponry
Most weapons and devices contain natural nanotech running through them. And as nanotech is used constantly it tends to appeal more powerful, therefore the weapon upgrades in damage, ammo-effeciency, speed, etc.

Nanoroid
When nanotech is used too much, it becomes a drug. Nanoroids were never used in the games, but a character from the old series Skidd McMarx was accused of using them.
