In the summit of a unbearably hot summer things just keep getting fucked up. On your way home from work yesterday your car sputtered and ran out of gas. You coasted off the road and your car joined the ever growing line of abandoned vehicles. People could no longer afford the fifteen dollar a gallon prices. It seems the choices are slim now. You can no longer afford to drive and eat. Hell , even if you didn't eat you still couldn't afford to drive. So...
You quickly take your car apart and fashion it into a weapon. A bulky heavy gun that shoots electrical bolts at the man. You try it out on a street sign and the bolt rocks the sign back, melting the painted message.
