City of the Dead

You drive up with the finger up already down the street going 100mph.The monster roars at you and starts to bear-run towards you.You swear as you turn down the street only to see the monster catch up to you.Suddenly a earsplitting erution happens and you see a explosion go of on the creature followed by smoke.You turn to look at morena and see grenades in her hand.She laughs and says"I was holding the pin down at the last second and threw it, lucky it didnt explode in side the car!".You look at her like WTF we almost died then get interupped by a voice in the car.You look around only to see that its the radio(when was the radio on?)The voice says"If you are a survivor, go on top of the apartment building on lexington st.You look to see a helicopter in the distance going to east.
