When Zombies Attack

Figuring that you've already went this far, you might as well continue the act. With a moan you stumble on after the zombies, curious as to where they are going. After a few minutes of tailing them, you still don't know where they're going. Then, at the edge of your vision appears a few S.W.A.T squads, all barricaded up by a road block. As the lead zombies near the barricade, you hear gunfire and they fall to the ground, torn by bullet-holes. This seemed to spark a chain of fire that ripped through the ever-approaching mass. The seemingly never-ending horde makes steady progress on the barricade, while hundreds of them continue to be mowed down by automatic weapon fire. Your place in line moves to closer to the front...better decide now!
