Zombie Apocalypse

What do one black dude, one woman, one biker, and an old Vietnam veteran have in common? They are the last four survivors in the city after the zombie Apocalypse. Armed with only two pistols a shotgun and a couple pipe bombs they must make their way to mercy hospital. They all start out on the roof of an apartment building and start blasting their way through the dozens of zombies that are downstairs. They make their way outside of the building and everything seems to be going fine until Louis ,the black guy, gets grabbed by a smoker ,a special zombie that grabs people and pulls them off with his tongue, and gets pulled into a car. As Louis slams into the car it sets the car alarm off. Zoey ,the woman, shoots the smoker to free Louis right before hundreds of zombies start coming to their location. As all four of them start running to the next safe house they are shooting charging zombies. One after another it seems like no matter how many zombies they shoot more and more keep coming. As Louis leads the team down an alley they find a ladder and climb up it and are just barely able to escape the zombie horde. They made it a total of 5 blocks and killed around 300 zombies. But they only made it to the first safe house, they still have to go 16 blocks to make it to the hospital.
