The first two levels of the video game act as an introduction and allow the player to familiarize themselves with the controls. After that, Dr. Sepulveda begins assigning tasks that span several levels to achieve a long-term objective. The first task involves clearing the virus population from and reactivating the Mines and Power Generator to provide resources for the Construction Yard. Once done, the Yard begins producing armored units, allowing the player to move on. The next task involves the reincarnation of Darwinians: the Soul Repository in the center of Darwinia collects the floating souls, and sends them down to the Receiver, where the Darwinians gather them and send them to the Pattern Buffer to be reprogrammed with the main Darwinian blueprint code, where they are sent to the Biosphere to be reborn. The player must clear the Viruses from all the facilities and reactivate them.
