Gun or armour? Those were important questions that everyone has to ask themselves once in their lifetimes. And now was Josh's moment. Stay with the dude with the gun? Or the dude with the armour? 
His mind was made up, however, when the said dude with the armour got out of the car and started ploughing through the ...ghouls? The name didn't sound quite right, but oh well. That was what they were calling them anyway. He grabbed the knife, and leapt out of the car after the armoured guy. Leapt out into a ghoul. 
Josh screamed and stabbed simultaneously. It hit the ghouls jaw, went in but the bone mostly deflected the knife. The creature kept coming, so he went for the eye. Joshua plunged his knife right in and the ghoul fell. 'Ok, ok they don't like eye stabbings. So I gotta go for the eye.' Then, raising his voice, he shouted the same warning for the others in the car. 'Go for the eyes, guys!' He dispatched of a few more like that, miraculously hitting the eye, albeit after a few tries in some cases. The horde of ghouls were starting to thin, but they were still much too strong to hold off. They had to get out. 
Josh chased after the guy with the armour, finishing off any dazed ghouls the human tank had left behind. 
'Quickly! We gotta get outta here!'
