"Spencer: ...a new superior breed of humans, given birth by the Progenitor virus. The Wesker children were entrusted with endless potential. Of them, only one survived. You.
Spencer always believed that the world was in an unacceptable state that would bring about the fall of mankind. He was motivated to usher a new world filled with a new human race in with himself as ruler of a utopia to change and evolve the Earth. Some time after Umbrella's founding, Spencer began putting his vision of spurring evolution through virus to work. He authorized the kidnapping of hundreds of children born of parents with above-average intelligence who were brainwashed into personalities suited toward serving Spencer. All of the children were given the surname "Wesker" after the director of the project. This project was also highly classified to the extent that it was not even included among the Umbrella Archives or in the U.M.F.-013 computer core.[notes 1] In addition, at least some of the project's candidates were aware of its existence before the Raccoon City Destruction Incident in 1998.[notes 2]
Spencer placed all candidate children into environments watched over by Umbrella and made sure that they received the best educations possible in all of the fields that they pursued. None of them were aware that they were being monitored constantly. Eventually, one Wesker child who showed particular promise would go to work for the very company that raised him, working at the Umbrella training facility in the Arklay Mountains. That child was named Albert Wesker. Spencer was pleased with his intellect and thought that his utopia would be flawless if all of the children turned out like him.
All of the candidates were injected with a prototype virus, some by the advice of "friends," some as part of a supposed health checkup, and others by force. Almost all of the Wesker candidates died outright due to this viral exposure, though several survived. The surviving children were programmed to seek out Spencer, their master. The project was projected to have a 93% success rate via Albert Wesker, although after his presumed death in the Mansion Incident, the success rate dramatically declined to 18%. During the Raccoon City Destruction Incident, the research notes are lost when the city was destroyed by the government, leaving Spencer with little to continue his vision.
By 2006, however, only Albert (Specimen no. 013) and Alex Wesker (Specimen no. 012) are still alive. After learning the truth about his origin, Albert killed his 'creator' and took over Spencer's plan to evolve the world, making a few adjustments to bring the plan to fruition at a faster rate in combination with his own plan to rebuild Umbrella. Albert was eventually killed by his nemesis, Chris Redfield, and his plan in the form of the Uroboros virus was destroyed with him. Alex Wesker, meanwhile would start developing the t-Phobos Virus and proceeded to use Sushestvovanie Island as the testing ground. She tried to commit suicide and take Moira Burton and Claire Redfield with her to the grave when they confronted her. However, the suicide failed and resulted in her body being immensely mutated. To make matters worse, a girl was implanted with a copy of her mind. Her reign of terror was brought to an end by Barry Burton and Claire Redfield killing the last of the Wesker children.

- ↑ Oswell E. Spencer, when revealing the project to Wesker, mentioned he lost the notes for Project W in the destruction of Raccoon City, and the U.M.F.-013, and by extension, the entire archives of the Umbrella Corporation, had been evacuated shortly before the city's destruction by Sergei Vladimir, as well as copied by Albert Wesker a few years later.
- ↑ Alex Wesker was shown in the file Report on Project W - August 28, 1998 to be fully aware of Project W, including that Albert Wesker was a candidate and that he had a likelihood of proving the project was successful before his presumed death during the Mansion Incident, while Albert Wesker himself had apparently never been aware of the project's existence, let alone his ties to it, until Spencer told him about it just moments before the latter's death at Wesker's literal hand.
