(Capcom's primary storyline)

Marco Wesker was one of thirteen members of Project W, a eugenics project started by Oswell E. Spencer to create a school of ideologically-similar Umbrella employees loyal to Spencer himself. Wesker is believed dead following his infection with the Prototype Virus developed to mutate the candidates and give them superhuman abilities.[1]
