You flip the switch on your autogun to full auto and empty the clip into the zombies as they close. You slap a fresh clip into your autogun and again spray the mob with hot lead. Unbelievably only one drops motionless to the ground. Adrian, your point man, calls out that he has found a passage to safety. As you load your third magazine you notice something coming at you from the left. With lightning reflexes, you block the slashing claws of the zombie that charged you. For rotting carcases, they can move!! You use the butt of your autogun as a club and crush the skull of the zombie. As it lies on the ground, you hit it a few more times upon the skull until it splits open and biege-brown sludge splatters on you. That should keep it down!!!
Now to find Adrian and that passageway. You run in the direction you heard him last; that should get some ground between you and the zombies.
