The oldest and most influential sci-fi TTRPG of all time meets the world’s most popular roleplaying game, with a complete 5e conversion by World’s Largest RPGs.

Get ready to enter your very own World Dungeon! Play as a familiar face, such as 🧨 Carl, 👑🐈 Donut, 🐊 Florin, 🐐 Prepotente, or build your own unique crawler, complete with a customizable class and race (if you survive to the third floor)!

"We watched Cthrion Uroniziir try to reduce the timescape into one singular universe, wiping out reality as we know it. She was defeated, and we see her cage every day."

Whether you’re a group of local heroes sent to investigate mysterious goings-on in the nearby haunted wood, or famous mercenaries plotting and scheming in the big city, the MCDM RPG makes building adventures and fighting monsters fun.
