The Dead Samaritan is a one page slasher-themed dungeon for Mork Borg or Slasher Victims.
It's a surprisingly arresting premise, and it works just as well for modern setting as it does for the Dying World. The overarching vibe is Jeepers Creepers-y, and the hook is that you spot an old man dumping a body and check to see whether someone needs help.
There's a few minor combats and NPCs, but they feel like they actually reduce the creepy vibe. The dungeon's ambiance does a much stronger job bringing the horror, and there's traps, claustrophobia, empty spaces, and body horror to keep things intense.
The central monster is maybe a bit strong (421 HP is a lot, and there's nothing that specifically conveys he's meant to be run from,) so GMs may want to play him as a recurring threat rather than a single climactic fight at the end.
Overall, I think this is a fantastic mini dungeon and great fodder for an atmospheric one-shot or mini-adventure. Pick it up if you can.
