[[File:Dospunus.jpg|thumb|150px|left|''An artificial planet made by so far unknown but well developed humanoids. We don’t know any more because it blocks our signals'']]Bacterial Takeover is set in a fictional Universe. Some of the [[Planets|'''planets''']] are the sameas in our Universe, like Mercury and Mars, and or Earth, which even has a population that is roughly similar to our world.

Most of the lore and information on the galactic history is revealed through planet and [[Minerals|'''mineral''']] descriptions.

Many of the planets that the player visits have been at some time have been inhabited by various civilizations, such as planet '''[[Atreria]]''' and '''[[Dospunus]]'''. Some parts of planet descriptions can change after entering a '''[[Black Hole]]''', which sends the player to an alternate timeline.
