Nanotech is a recurring technology serving as a gameplay element in the Ratchet & Clank series. It is a technology that consists of tiny nanomites (nanobots) that live within organic life forms, robots and other technology such as weapons and armor, to perform repairs and healing, or other functions such as weapon upgrades. Nanomites are also absorbed from defeated enemies: the more powerful the enemy, the more nanomites are absorbed.
Nanotech is primarily used as a health, and serves as a means by which a character's life is gauged, and reaching zero nanotech causes the character to fall unconscious or die. A player character's maximum nanotech can often be upgraded through various means. One way is through defeating enemies; when enough are defeated to fill a nanotech level meter or experience bar, the maximum nanotech is increased (and current nanotech is restored to maximum) as nanomites are absorbed into armor from defeated enemies to improve the maximum nanotech. In other cases, collected items can improve maximum nanotech.
Aside from serving as health, nanotech also allows weapons to upgrade. Nanomites absorbed from defeated enemies are used within weapons to upgrade; this is indicated by a weapon's level meter which, when filled, improves the weapon a level until it reaches its maximum.
Ratchet & Clank
In the original Ratchet & Clank, nanotech exists solely to replenish Ratchet and Clank's health. Ratchet can initially carry a maximum of four nanotech, and each hit takes away one nanotech. At the Kogor Refinery on planet Orxon, Ratchet can purchase supplements that, when drank, expand his maximum nanotech. These supplements are Premium Nanotech for 4,000 bolts, which expands his maximum nanotech to five, and Ultra Nanotech for 30,000, which expands it to eight. Clank, however, always has four nanotech.
Nanotech is replenished by breaking nanotech crates, which restore a single nanotech.
Upgrading to Premium Nanotech unlocks the bronze trophy Hit Me More! while upgrading to Ultra Nanotech unlocks the silver trophy Nano This! in the high-definition re-release of Ratchet & Clank, also available in Ratchet & Clank Collection.
In Going Commando, Ratchet is suited with commando armor from MegaCorp that allows him to absorb nanomites from defeated enemies. This allows Ratchet to increase his maximum nanotech beyond the initial four up to 70. Each time the maximum capacity expands, it fully replenishes and causes a flash of elecricity that damages (and in many cases destroys) all enemies on screen.
Ratchet's nanotech can expand 10 times more up to 80 with hidden nanotech boosts. 10 of these can be located throughout the game: one on Endako, one in the Feltzin System, one on Notak, one on Tabora, one on Dobbo, one on Joba, one on Todano, one on Boldan and one on Snivelak. These are necessary for obtaining the skill point Nano to the max!.
As in the previous game, Clank has four nanotech that cannot be increased. Nanotech is also restored from blue nanotech crates, though Ratchet can find larger pink nanotech crates which restore four nanotech. In challenge mode, the amount of nanotech restored from both quadruples; blue nanotech crates restore four while pink nanotech crates restore sixteen.
Nanomites are also absorbed by weapons, allowing a weapon to pick up nanomites by defeating enemies with it. After a weapon's upgrade bar is full, it upgrades to a new, more powerful weapon. This applies to all weapons developed by MegaCorp with the exception of the Zodiac and the Clank Zapper. A second upgrade can be purchased a MegaCorp vendors, upgrading the weapons to Mega versions which can be upgraded with nanomites a third time to reach maximum capability.
Up Your Arsenal
Up Your Arsenal features nanotech used similarly to the previous entry, with nanomites having a more opaque appearance. The flash of electricity that previously occurred every time Ratchet's maximum nanotech capacity increased instead occurs every 10 times it increases. The maximum nanotech is also set at 100, which can be expanded to 200 in challenge mode; as before, Clank always has four nanotech. Nanotech crates also grant nanotech to Ratchet at a varying rate rather than a set number.
An item called the nano-pak can also be acquired, which stores unneeded nanotech and releases it to the user when their nanotech is low.
Nanomites are also absorbed to upgrade weapons, but can now upgrade four times from level 1 through to 5, in which the first four upgrades incrementally improve the weapon while level 5 drastically transforms it. In challenge mode, once a weapon reaches level five, the Mega version can be purchased to upgrade it three more times, to Giga, Ultra and finally Omega at V8. This applies to all Gadgetron and MegaCorp weapons with the exception of the RY3NO which can only be upgraded to level 5.
In multiplayer, players have non-upgradable nanotech which can be restored with nanotech crates or by standing on nanotech pads in Siege mode.
Deadlocked uses nanotech of a unique grey-orangeish color, and with nanomites referred to as "nanodrones". Nanotech is used for health in a similar fashion to Up Your Arsenal. Ratchet's maximum nanotech can be increased up to a maximum of 999.
Vox Industries weapons can be upgraded incrementally as far as level 10, though purchasing the Mega version in challenge mode allows them to be upgraded up to level 99. Additionally, equipping alpha mods such as the XP mod allows weapons to gain up to 500% extra XP (nanodrones absorbed) towards upgrading weapons and health, depending on how many mods are equipped.
In cooperative mode, both players share their weaponry, and therefore share nanotech used to upgrade these weapons. Experience to upgrade nanotech health is also shared. If either player runs out of nanotech, they will respawn after six seconds provided their companion is still alive; if both die, both are sent to the checkpoint.
In Going Mobile, Ratchet has 20 nanotech with health laid out in the style of Going Commando, but cannot be upgraded. Weapons can be upgraded to V3.
In Size Matters, Ratchet's nanotech could reach a maximum of 50, and up to 75 in challenge mode. His weapons had four levels from V1-4, and a Titan upgrade to upgrade them to V8.
In multiplayer, blue nanotech crates restore at least a quarter of the player's nanotech, while yellow nanotech boxes upgrade weapons, and orange nanotech boxes grant weapon mods.
Secret Agent Clank
Secret Agent Clank gives Clank, Ratchet and Qwark a nanotech level, where Clank and Ratchet can upgrade their levels by defeating enemies. Ratchet has a maximum of 90. The weapons upgrade in an identical fashion to Size Matters, though Clank's weapon upgrades are known as Proto upgrades rather than Titan upgrades.
Tools of Destruction
In Tools of Destruction, Ratchet has a maximum nanotech of 999, upgraded in increments of five. Each time his nanotech level bar fills completely, a flash releases that destroy nearby enemies before upgrading.
Weapons can be upgraded to level 5, and in challenge mode, an Omega version can be purchased to allow them to upgrade five more times to Level X (10).
Quest for Booty
In Quest for Booty, Ratchet's maximum nanotech capacity is 20 units. Upgrading Ratchet's nanotech also releases a flash of energy that destroys nearby enemies and refills health.
Weapons, as in Tools of Destruction, can be upgraded up to level 5, though there are no Omega upgrades as there are no vendors or challenge mode.
A Crack in Time
In A Crack in Time, Ratchet again has upgradable nanotech. Ratchet gains experience points (representing absorbed nanomites) by defeating enemies or collecting Zoni, and filling a bar improves Ratchet's nanotech up to a maximum of 199.
As with Tools of Destruction, weapons can be upgraded up to level 5, and in challenge mode, an Omega version can be purchased to allow them to upgrade five more times to Level X (10).
All 4 One
In All 4 One, Ratchet, Clank, Qwark and Nefarious all have nanotech as their health, though they do not absorb nanomites and it is not upgradable. Ratchet's maximum nanotech level is four. Nanotech can be found in nanotech crates, and when a teammate is low on nanotech, another player can use extra nanotech that has been stored to heal them.
Unlike previous games, weapons cannot be upgraded using nanotech as nanomites are not absorbed.
Into the Nexus
Ratchet's weapons can be upgraded twice up to V3. Obtaining the Omega version in challenge mode allows it to be upgraded further to V6.
