The city is a swamp. Literally. When the water is up, the streets are teeming with gators. That's not Ed's biggest problem, though. 

An unfortunate chain of events have plunged his life into a downward spiral. Deep in the dark and maddening depths of the city, he'd made a deal with someone he shouldn't have. Now his soul is damned.

The undead begin to stir, having taken notice of him. There's a price on his head, which have drawn the bounty hunters, guns ablaze. Time are tough.

Not to mention all the damn gators everywhere.
