Walking through the desolate, once-thriving city, you grip the straps of your backpack tightly, wary of your surroundings. Then, a guy casually hops over a wall onto your side of the street. Coincidentally passing through, he wears earbuds blasting heavy metal while holding a strange long, black case.

He looks over at you through his sunglasses and pops out one of a bud. "Hey buddy, you lookin' pretty f*ckin' hopeless, mind if I join you?" he called out casually. You can't help but eye him suspiciously, fingers tightening around your pack straps.
