Zombie Horde: The War Begins

Game description:

"You are surrounded by a horde of ugly zombies and mutants. You must survive until reinforcements arrive, or you will be devoured. You are armed with only a pistol, but you must use your wits and skills to stay alive. You must find a way to escape the horde, or you will become one of them. You run through the streets, bullets flying past your head. You duck behind a car for cover, but the zombies are closing in. You have to think fast. You see a window on the second floor of a building. You quickly climb up the fire escape and break the window. You jump inside and land in a dark room. You are safe for now, but you know the zombies will find you eventually. You have to find a way to escape. You look around the room and see a door. You cautiously open it and peer out. The hallway is empty. You quickly run out of the room and down the hallway. You come to another door. You open it and find yourself in a stairwell. You run down the stairs, the sound of the zombies' footsteps getting closer. You reach the bottom of the stairs and find a door leading outside. You open the door and run out into the street. You are free! You run as fast as you can, the zombies' screams fading behind you. You have survived.
