Twenty Candles for the World's Largest Dungeon

World’s Largest RPGs is preparing to unleash the 20th anniversary edition of the World’s Largest Dungeon.

Launched in 2004 by by Alderac Entertainment Group, the original edition of The World's Largest Dungeon was a Dungeons & Dragons campaign set, beginning to end, in one ginormous dungeon. With a page count in excess of 800 pages long, it remains one of the largest, most gloriously ambitious campaigns ever published in one tome.

Now retooled for 5e, this shiny new Platinum Edition refurbishes, revitalises and relaunches this iconic dungeon. As well as the flagship dungeon, World’s Largest Dungeon is said to include ‘new content, exclusive miniatures, stunning maps, and expanded adventures for a new generation of adventurers’.

This updated edition will also boast ‘the latest rules, enhanced editing, and stunning new artwork and maps,’ all of which have been curated by World’s Largest RPGs’ publishing partner, Strange Owl Games. Not enough? Then how about:

16 new boss miniatures

Curated miniature sets from Reaper Miniatures

16 poster-sized maps

Over 1,600 original encounters

Exclusive Fanroll dice

An audiobook by AudioRPG

New stretchgoal content

Secret Door Encounters featuring guest designers from iconic worlds like Dragon Kings, Fading Suns, Torg Eternity, Thieves' World, and more.

The World's Largest Dungeon launches 13th May, 2025. Visit the prelaunch page now to receive a free and exclusive badge*.
