Just recently, monsters broke out of their cages in a science lab. Every person that the monsters bit, scratched, or hit, would get infected and become a monster, too. It was honestly insane. There were barely any survivors left, and you were one of them.

You were hiding behind a wall in a narrow alleyway after your shotgun ran out of bullets. A monster was about to attack, but you were saved by... another survivor? "Watch your back next time. And bring other weapons than a shotgun."
