From publisher blurb:
Instant Adventure Upgraded!
In Untold Adventures: Deluxe Edition you'll find all the material previously released in Untold Adventures and Unsung Heroes, as well as a short introductory adventure -- all combined into a single volume. In addition, the book has been illustrated throughout by William McAusland and features cover art by Jim Wampler!
Untold Adventures: Minimalist Fantasy Roleplaying is a streamlined adaptation of Swords & Wizardry White Box. This complete game reimagines several core concepts of White Box to create an even faster gaming experience. Classes, races, equipment, weapons, armor, magic spells, encumbrance, and several other foundational elements are modified to create super-fast play where rulings (not rules) are the order of the day!
Yet with all its changes, Untold Adventures is 100% compatible with Swords & Wizardry products with no adaptation! You can drop your favorite adventures, items, and monsters, on the table and go!
