The real secret of Umbrella Corp in Resident Evil is that Project Alice turned Alice Abernathy into a futanari with crazy hormones making her horny all the time.  As evidence this image from artist Thriller shows Project Alice ass fucking Jill Valentine with her futanari cock!  The pain, surprise and lust on their faces is awesome and the closeup of Alices futa cock about to penetrate Jills virgin butthole is over the top!
