Nanotech

&nbsp Nanotech was technology that consisted of NanoMites (NanoBots) living in many living organisms, Robots and other technology such as weapons NanoMites then repaired the being they were inside, or performed other tasks such as upgrading weapons. Originally Nanotech was just used to improve health, however as technology advanced weapons became more and more upgradable.

Nanotech Crates
NanoTech Crates contain NanoMites surrounding each other making a sphere in a 5g. tank. When NanoTech is aquired the more nanotech you have the more damage you can take.

Arsenal
Up Your Arsenal functioned very much the same way as Going Commando in regards to Nanotech. However, the flash of electricity that used to occur at every expansion of Ratchet's capacity only happened every ten times. The maximum amount of Nanotech is 100 in a normal playthrough, and 200 in Challenge Mode.

Nonetheless, Up Your Arsenal introduced new bonuses regarding its weapons: they can upgrade four times (from level 1 to level 5), and once a fifth upgrade was bought at a Gadgetron vendor after the game was completed, could be further upgraded to level Omega (level 8). The only weapon that could not reach this level was the RY3NO, which only goes as far as level 5, at which point it became the RYNOCIRATOR. There was also a gadget called the nanopak which could collect unneeded Nanotech and release it to the user when their Nanotech was low.
