Selfish: Dungeon Edition

It's a Selfish dungeon crawl where everything wants you dead, and the way out’s probably a trap... have fun!
Trapped in a dungeon with monsters, traps, and your "trustworthy" friends? Sounds like a great time.
You’ve got limited light, zero loyalty, and a slim chance of escape.
Oh, and if you die? No worries—you’ll come back as a vengeful undead to mess with the survivors.
Only one player can escape, assuming they don't make a horrible decision at the last second.
Good luck.
