• Wesker and Birkin move the t-virus into the third stage and look toward creating the ultimate Bio-weapon.
• The Tyrant proves to be an obstacle for the research, although the t-virus is well suited to creating zombies and hunters, to create a Tyrant the infected needs to contain a certain, rare gene. In short – only one in ten million hosts would become a Tyrant. The research comes to a standstill.

• Feeling the pressure of competition, particularly from the European branch. Wesker quickly demands a sample of the NE-α Parasite, despite Birkin's opposition, in order exploit it for his own success. Spencer makes the impossible happen and within just a few days Wesker and Birkin have a sample of the parasite. Before long Wesker and Birkin add a long list of deaths to their research, as the parasite kills most of its hosts within minutes. ^[2]

• Wesker, desperately trying to take control of the NE-α, decides as a last resort to use Lisa Trevor as a host for the NE-α.^[2]

• Lisa Trevor is administered with the NE-α, and the sample disappears the moment it is injected into her. Lisa absorbs the properties of the parasite into her own genetic make-up.^[3]

• Birkin, now obsessed with Lisa, ignores all the previous research and starts fresh. He learns that within Lisa is the first ever known existence of the G-virus. ^[3]
