The heavily armoured apc plowed through burnt-out wrecks of cars as it sped towards the train station.
"Look!" The mysterious new cop yelled through the vehicle's com, "Soldiers to the left!". Sure enough, several of the grey armour-clad cyborgs aimed at the apc with a mounted gun.

The apc's main gun snapped up and pointed at the closest combine.
"Shit!" Is yelled as it was torn to pieces by a hail of heavy pulse rounds, crimson fluid staining everything within metres. As the other soldiers scattered for cover, Chau aimed the apc for their leader, another elite. The vehicle plowed right through it, not even slowing down as a hundred kilograms of armour plating flew through the air.

As the last combine fell to the floor with a large hole through his stomach, Chau killed the apc's engine. Opening the door and jumping out, she strode to the back of the tank and pulled open the door to reveal the shape of a rogue CP sitting in a seat, manning the gun through a small screen on the wall.
"Get out!" Chau yelled, grabbing the traitor by the collar.

"I'm here to help you!" The combine cop choked in surprise as it fell from the back of the apc, its vocoder making it voice seem even more strained.
"I can't trust you. For all I know, you're a combine spy who kills stray citizens!" Chau replied, putting her empty ar2 to the police's head.
The traitor reached up to its mask and gripped the seal.
"Well, lets see then." As the cop reached up and pulled up on the mask, it popped off with a small hiss, revealing the true person inside. And to Chau's horror, she recognised him.

AN: Short chapter today. I don't have enough time to write a long one. I will reveal who this mystery cop is with the first word next chapter (which might be later today...)
