The Cargo

It had already been a long week for Sanri, she had just come back from a short delivery mission, little had she expected to be given a job so soon.

“This Job is your biggest one yet, our client needs you to deliver an item discreetly from Terminal-Jewel to Terminal-Lasteye.” Jemini said.

“Jewel to Lasteye? That rugged train?” Sanri said.

“The payment will more then make up for it, there is a contact in the train who will already pay you a small bonus to get your bearings once you’re inside the train, they are with the Rajas, besides that you’ll be on your own for this job. Oh and do NOT open the cargo.” Jemini Said.

“Fine.” Sanri said as she walked off to her locker, she took out a duffel bag and checked to ensure it had everything, a knife, a handgun with four magazines, a flashlight, depression pills, cigarettes, some thick cotton and spare clothing.

She also slowly put on a thick five layered suite which detachable layers, then walked out in to the cold, the handheld thermometer read out [WARM: -50 degrees Celsius] she then snapped a few pieces of her top layer, which then opened it up and she felt her body temperature drop to a more sustainable level.

The journey to the automated train terminal did not take that long, a 25 minute walk trough the dug-out snow pathways was an easy task. But getting in to the terminal without issue is another beast.

She approached the only remaining entrance not destroyed by previous turf-wars or the Drop. The gate was roughly 7 meters wide, it had two 12.7mm turrets on the left and right respectively, the gate also had four heavily armed guards with shotguns and teargas.

“The toll for using our turf!” a man with a square brim barked at Sanri.“They must not know my face.” She thought to herself as she took out a sheet of metal with an insignia of a two headed wolf. “My apologies! OPEN THE GATE!” the brimmed man said. As his words reached behind the gate, a loud cranking noise became aloud as the 6 meter thick composite alloy gate doors began to turn.

As the gate did open and Sanri was halfway trough the entrance, screams began to erupt from behind her as red clad people with pistol began to storm in to covered positions as they engaged fire on the guards by the gate. By the time four shots had been fired, the turrets began ripping at 1200RPM towards the assailants, the bullets glanced of the guards by the gate, causing one to slightly flinch in pain. The following ten seconds was a hail of screaming and gore covered by the sounds of a heavy machine gun ripping trough bullets.
