main character super power of i can't get infected because i have the genes that make me resist zombie infection because im the protagonist ACTIVATE. Well sherry and jake have an explainable reason as to why they don't (right?)
It actually says in the files that a Herb boosts immunity to the viruses. That would explain why All RE characters are alive despite being in close contact to the virus several times. Basically the game says taking the Herb not only heals you but lets you fight off the virus with your anti-bodies just like Jake.
I have an answer to everything whether its a good answer is entirely irrelevant
