Dead Russia

(If I decide to open this as an RP: http://www.haloroleplay.com/t1192-dead-russia#85080 )
(If I don't decide this is going to be an RP, it's going to be a story about my character, Siren.)

Siren paused at the blown-out section of the wall. She was in the center of Moscow, in one of the largest residential areas, and there were a lot of both hunters and berzerkers outside. She had her rifle, but against that many of them, she might as well fight with a stick. She could go across the hole, but that risked her being seen by the horde outside; something that would probably get her ripped apart. It was also freezing, she noted beneath her balaclava, and if she stayed there she was likely to freeze. A quick glance out of the opening showed her that she would definitely die if she got caught. One or two, she would've just shot them, but outside there were over sixty of them.
Three seconds... She told herself mentally; giving a time limit would force her to act, something most Scavengers did when they were indecisive; indecisiveness got you killed.
Two seconds... She needed to take the risk, there was a time limit on her job. The medicine she was carrying needed to be at the town by sunset, or she'd have failed. She never failed.
"One second..." She whispered, her breath forming mist in the cold Russian air.

She stepped out and for a brief second she was completely exposed. Anything, man or beast, could have seen her. Then she was back in the shadow of the wall. Hidden, just like she should be. She listened for the distinctive scream of a berzerker horde seeing prey, praying that she hadn't signed her own death sentence. The scream never came, and she breathed a sigh of relief, sneaking along the wall until she was safely away from the group of berzerkers. She straightened up and set off at a slow jog towards the town, the snow crunching under her boots, her VSS never left her hands, as peaceful as the empty and snowy houses seemed, there was always something waiting to tear out your throat in the city, a fate Siren had become legendary at avoiding. She enjoyed her own status. People loved her for what she was capable of. She wasn't a narcissist, however, she liked helping those who couldn't help themselves. It was her duty to help them, especially if nobody else could.
