- Purchasing a new colony increases the price of all colonies of the same type, but the increase to production remains the same.
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.
Except for Petri Dish, all Bacteria colonies are unlocked once the player has accumulated Bacteria equal to the base cost of that colony.
Colonized planets work identically to regular Bacteria colonies, but have the additional requirement of the player having previously destroyed at least 8 planets. This is not reset when you enter a Black Hole, so you should be able to immediately purchase colonized planets as long as you have sufficient Bacteria.
Colony Price Calculation
After purchasing a colony of one type, the price of that colony increases. The colony price can also be affected by certain Gene Strand upgrades. 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
