I didn't get Umbrella much at all anyway. Like why in the world would people buy something that creates Zombies? I just think that's pretty derpy.

infect your enemies with zombie virus, they will be too busy fighting themselves to focus on you.

Who were their enemies though? And that just made practically the whole world turn into Zombies... so now the world is just bleh.
