Tetsuya Foster lurched out of his home a zombie... After I researched the cure, inoculated everyone in town, and created an aerial distribution system for said cure.
When one of the Germans took a bazooka to the face, shrugged it off, and continued to walk on and kill my spec ops guy in single combat... I knew I was done.
I see all the bullets flying, and can't help but think that everyone on the map should be dead in, like, 4 seconds due to collateral damage.
(Also, Sanders and Ronald, I can confirm, pop up freaking everywhere.)
