DoppelDungeon, or, How I Learned to Stop Worrying and Split the Party

Publisher's blurb: DoppelDungeon, or: How I Learned to Stop Worrying and Split the Party is a single-session dungeon intended for parties of 3-6, and is both system and setting agnostic. Friendships will be tested, loyalties will be questioned, and suspicions abound when the party finds a mysterious stairway leading into a mountain where nothing is as it seems. Not even their friends! Can your party survive the uncertainty and distrust on top of the traps and monsters? Light your torches, sharpen your blades, and head into DoppelDungeon to find out!
