Doors to Dungeons

Chris was down on his luck, no job, kicked out of the house by his stepmother, not even having time to grab his phone or wallet. His bad day only gets weirder when he encounters a mysterious door in the middle of a parking lot and then finds himself thrust into the depths of a Hell Difficulty Dungeon. Now he has to survive the monsters, the Dungeon and his own mind as he fights to get back home, even if only to see his father and sister again.

But what happens when he succeeds and emerges from the Dungeon? How has the world outside changed in his absence? How has his time in the Dungeon changed him? And what was that about him probably being the strongest human on the planet? At least currently.
