you were roaming around the apocalyptic city, avoiding making excessive noise to not attract any strays or hoards of zombies, you notice a guy atop a building, screaming and running around, running towards you as he yelled, a hoard of zombies jumping and piling behind him

"RUUUN! GO GO GO, RUN!"

he grabbed your arm, running as fast as he could as he threw a few shots back at the hoard to slow them down
