It's a day like any other since they hit Earth. Always running to the next hideout, shooting your way through wave after wave of these… things. They don't even scare you anymore, these husks; their bodies more wire and metal than flesh, pawing and screeching at anything with a puls. The other survivors are used to them too now, some even making a sport out of how many they take down while on the move each day.
Today you join them, like you have done for weeks. You're in the lead, but then you have an unfair advantage, a nearly brand new modded Phalanx, while the rest of them are running around with shitty Predators at best. A well placed shot, right in that sweet spot between the eyes, and they heads simply vanish.
You manage to kill four, one of them goes down inches away from Jess, who really should be checking his six, instead of Val's. As you start to move out, he points to a garbage heap. There on top, must be one of the last group. Couldn't keep up, huh?
You take your time aiming, careful not to waste ammo on just one straggler, when it turns and looks straight at you, through you. It hits you then, for the first time since your world exploded around you.
This used to be a human. Months ago, or maybe days, it had a name. It was someone's child, maybe someone's husband or wife, someone's parent even. Now it's shamblig towards you, no more alive than the gun in your hands. Just another weapon. For a split second, you imagine becoming a husk yourself, a construct of death and endless screams, or even worse, something that remembers but has no control. You would have begged for the bullet. Maybe it does too.
