Nanobots
Nanobots are a resource that is unlocked after destroying the fifth planet.
The primary use of Nanobots is to kill the last percentage of a planet's population, which is usually harder to infect by using only Bacteria. Just like Bacteria, Nanobots are lost when attacking a planet or entering a Black Hole.
Nanobot Production is unlocked after destroying the fifth planet. Nanobots can be produced by Scientists.
After researching Quantum Robotics at the Dark Matter Institute, the player has a 0.1% chance to produce a Nanobot on tap. Dark Matter Institute also has the Dark Engineering technology, which increases Nanobot strength by 25%.
After Atreria, all planets have Nanobot resistance, which reduces Nanobot strength. Nanobot strength is not influenced by added infectivity bonus.
