It would be a horror movie.
A group of college students have a barbecue party at the Firelink bonfire. After drinking too much they play truth or dare with one of the empty Estus flasks. The unlucky loser chooses "dare" and has to run to the graveyard to pick up a heavy sword. Before reaching it he gets too intimidated by the assembling skeleton army and runs down some stairs. He calls for help and his friends come to escort him back to the bonfire. One of them light-headedly tries to attack a skeleton but gets parried like a scrub and dies. The rest flees into the Catacombs. On their descent the group is decimated by the various dangers this area holds in store. One event is especially bloody and will later be called "The Bonewheel Massacre" by the newspapers. The few survivors, two girls and a guy, find a mysterious mist. They are scared, but the approaching rolling sound behind them leaves them with no choice. Right behind the fog a strange message is written on the ground ... "Tough enemy ahead". One of the girls panicks. Convinced there would be an even more horrible death ahead she turns back and exits the fog again, dying moments later. The other two jump down into the coffin. The remaining girl breaks her ankle and is unable to walk. "Stupid unavoidable fall damage, fuck this ga- " are her final words as she gets hit by a fireball. The guy doesn't get seriously injured by the fall, but loses his glasses. Almost blind in the dark arena he starts running around spamming r1 in all directions. Unfortunately, he stumbles and falls to the ground. Fortunately, he knocks over Pinwheel while falling. There is a strange noise, then ... YOU DEFEATED. Happy and a little bit confused his journey continues. The darkness of the Tomb of the Giants doesn't bother him, shiny stones on the ground show him the right path. Eventually he hears a voice, a human voice! "Good day! You look reasonably sane ..." He asks for help, but this voice only offers him some random treasure. That upsets him and he calls the other person a cleric. And this is how the last one dies as he takes a Winged Spear to the face. The movie ends with Patches grilling some sausages at Firelink.
