100% Infectiousness.

100% Lethality.

Well, it happened. The SCP Foundation lost control of an important asset. Someone managed to get infected and spread this highly infectious disease. It was quickly contained within the facility...but a few specimens managed to escape. On the train they went, and by the time they reached Shi no Miyako, they had a light snack. Then, all their victoms had snacks of their own. The whole train unleashed a furious zombie wave upon the city (I was thinking Train to Busan style). That was a few days ago. Now you’re stuck in a city full of zombies. It’s not airborne or waterborn, but getting bitten means it’s all over. You’ll be a mindless zombie within 3 hours. All bridges are barricaded. All trains have left the city. 100% chance of being shot on site if anyone tries to leave. No. Matter. What. 

Lucky you. You missed the last train out and have to survive in Shi no Miyako. Time to survive. Will you find other survivors? Or are you on your own until the cure is made?
