How far can you go without getting bitten? I was doing another run just for fun lately and managed to get through the supermarket, but then they raided the hive and I dieded.
EDIT: To the OP:
Breath of the Wi... oh wait.
Sin & Punish... dangit.
Jet Force Gemini!
It's been a while since my last playthrough... But I think I fucked it up around the gates of Buckingham Palace, just before the machine gun section xD
... Damn, I really need to play ZombiU again. Such an experience...
EDIT: Oh, that part where you died is hard. I just remembered. There was one of those zombies that keeps calling more zombies, right? I think I just ran for my life right to the underground. No looking back xD
