Anna sits in the cold trench, snow filling each dip and cranny around her. Her thick, winter clothing and the trench itself prevents the wind from reaching her, but her teeth chatter as she shivers with each breath. She pulls her jacket closer, trying to conserve her body heat with her arms crossed. She can feel the cold metal of her rifle beside her as she takes a glance at her surroundings scanning for threats. The world has been at war with an Alien race for years.
