From Bacterial Takeover
Jump to: navigation, search
Purchasing new colonies is the main means for increasing BPS and BPC. Colonies cost Bacteria. New types are unlocked when the player has accumulated Bacteria equal to the base price of the next available colony.

Purchasing a new colony increases the price of all colonies of the same type, but the increase to production remains the same.
Before purchasing colonized planets, there is an additional requirement of having previously destroyed 8 planets. This is not reset after entering a Black Hole.
All colonies and regular colony upgrades are used up when attacking a planet or entering a Black Hole. Gene Strand upgrades to colony production are only lost when entering a Black Hole, but BPC and BPS bonuses from the Dark Matter Institute and Premium purchases are permanent.
The effective production of colonies is also influenced by the equipped Evolved Bacteria, which can boost the total BPS, idle BPS, or reduce colony price.

Colony Types

Bacteria Guns

Bacteria Gun is available for purchase from the very beginning of the game.

Unlike other colonies, Bacteria Gun adds only to the player's BPC.

Bacteria Colonies

Except for Petri Dish, all Bacteria colonies are unlocked once the player has accumulated Bacteria equal to the base cost of that colony.

All Bacteria colonies only add to BPS, but some colony and Gene Strand upgrades can boost the player's BPC by a percentage of the total BPS.

Colonized Planets

Colonized planets work identically to regular Bacteria colonies, but have the additional requirement of the player having previously destroyed at least 8 planets.

Colony Price Calculation

After purchasing a colony of one type, the price of that colony increases. It is calculated according to formula

NewPrice = BasePrice × PriceCoefficientColoniesOwned × PriceDiscount
  • NewPrice - current price of the colony
  • BasePrice - the original price of the colony
  • PriceCoefficient - an arbitrary number in the range from 1.07 to 1.098. Each colony has a different Price Coefficient.
  • ColoniesOwned - number of colonies that have already been purchased
  • PriceDiscount - calculated from the reduced colony price bonus that is obtained from Evolved Bacteria
