- 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.
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.
