The main goal in Bacterial Takeover is to destroy as many planets as possible.
Attacking a planet uses up all [[Resources#Bacteria|'''Bacteria''']] and [[Resources#Nanobots|'''Nanobots''']], and resets [[Colonies|'''colonies''']] and [[Upgrades|'''bacteria Bacteria upgrades''']]. Destroying planets unlocks new upgrades and features, such as [[Research#Colony Irradiation|Colony irradiation]] or [[Research#Nanobot Production|Nanobot production]].
After entering a '''[[Black Hole]]''', the player enters an alternate timeline where none of the planets have been destroyed. The planets in the alternate timeline have the same stats and defenses, but can unlock different features. For example, destroying the fifth planet after the first Black Hole unlocks [[Research#Bacteria Irradiation|'''Bacteria irradiation''']].
The first 34 planets have unique descriptions and artwork, but the others are generated automatically.

=Planet Attacks=
The player can attack every planet an unlimited number of times until it is finally destroyed.
A planet counts as destroyed if its remaining population has been reduced to 0. However, it's not possible to attack a planet if the player cannot destroy enough population to gain even 1 [[Gene Strands|Gene Strand]] or if he has less than 1 . The amount of population that is destroyed during the attack is equal to the total of the population destroyed by [[Resources#Bacteria|Bacteria]] and [[Nanobots]]. ==Using Bacteria==The formula that determines the percentage of population that will be destroyed by [[Resources#Bacteria|Bacteria]] is based on the [[SIR Model|SIR model]] for the spread of infectious diseases. For this reason, it can sometimes take more Bacteria to kill the last 1% of the population that it was required to destroy the first 99%. The total number of Bacteria required to destroy 100% of the initial population is calculated according to the following formula: '''BacteriaNeeded = Population × 9.9 × 15<sup>[[Planets#Shields|ShieldLevel]]</sup>''' ==Using Nanobots=={{nanobot formula description}}
==Rewards==
Killing a percentage of a planet's population earns [[Gene Strands]].
If the player has already unlocked [[Minerals]], completely destroying a planet also has a chance to obtain drop a [[Minerals|Mineral]] native to the current planet.
Destroying planets also unlocks new game mechanics and [[Upgrades|upgrades]].
==Reset==
Both attacking and destroying planets resets certain [[Resources|resources]], [[Upgrades|upgrades]], and bonuses.
<u>Attacking</u> a planet '''resets''':
* [[Resources#Bacteria|Bacteria]]
* [[Colonies|Bacteria Colonies]]
* [[Upgrades#Bacteria Upgrades|Bacteria Upgrades]]
* [[Nanobots]] (if the planet was not destroyed)
<u>Attacking</u> a planet '''does not reset''':
* [[Gene Strands]]
* [[Upgrades#Gene Strand Upgrades|Gene Strand Upgrades]]
* [[Evolved Bacteria]]
* Bonuses from [[Planetary Research]]
* [[Achievements]]
* [[Diamonds]]
* [[Resources#Scientists|Scientists]]
* [[Resources#Dark Matter|Dark Matter]]
<u>Destroying</u> a planet '''resets''':
* Bonuses from [[Planetary Research]]
<u>Destroying</u> a planet '''does not reset''':
* [[Nanobots]] that were not necessary to destroy the planet
=Planet Population=
<div class="page_icon">[[File:population.png|80px]]</div>Each planet has a larger population than the previous one. Population can reach [[Large Numbers|'''large numbers''']] in early game, which are displayed using [[Large Numbers#Abbreviations|abbreviations]] or [[Large Numbers#Scientific Notation|scientific notification]], if it has been enabled in the settings menu. The higher the population, the more '''[[Gene Strands]]''' can be earned from completely destroying the planet.
Even though planet population is not technically a form of defense, planets with higher population are harder to destroy, because they require additional bacteria[[Resources#Bacteria|Bacteria]] to infect.
It's possible to view the population of previous planets since the last [[Black Hole]] in the '''Destroyed Planets''' panel.
===Nanobot Resistance===
Nanobot resistance reduces the effectiveness of [[Resources#Nanobots|Nanobots]]. There are 4 tiers of Nanobot resistance. {| class="wikitable" style="text-align:center;"|-! scope="col" style="background-color:LightCyan;| Planet Number! scope="col" style="background-color:LightCyan;| Nanobot Resistance|-
Nanobot resistance coefficient is determined by Nanobot resistance and it is used to calculate the effectiveness of Nanobots when [[Planets#Planets#Using_Nanobots|8-9attacking the planet]].|low<br><br>|----

[[File:Shields.png|150px|left]]
===Shields===
::::::::Starting with '''[[Tesmielara]],''' all planets have shields, which makes them harder to destroy.
::::::::The shield level increases by 1 for each planet. So the next planet after Tesmielara will have Level 2 shields and so on.
::::::::So Shields multiply the amount of [[Resources#Bacteria|Bacteria]] needed to destroy the next planet after Tesmielara will have Level 2 shields and so onby <code>15<sup>x</sup></code>, where <code>x</code> is the shield level.
