→Bacteria Upgrades
Bacteria upgrades give various multipliers to global [[BPS]], [[BPC]], as well as increase the production of different [[Colonies|'''colonies''']].
Most BPS upgrades can only be bought once, but some are iterative. Iterative upgrades usually become available after the player has bought 200 of one colony type. Afterwards, they can be bought indefinitely per 25 new colonies have .
The player unlocks new bacteria upgrades by purchasing more colonies. After purchase, bacteria upgrades cannot be sold or disabled.
