Playing Super Dungeon Explore requires a base set - Super Dungeon Explore (First Edition) or Super Dungeon Explore: Forgotten King (Second Edition). The base sets contain map tiles, heroes, bosses, creeps, and spawn points, as well as the generic tokens, dice, and cards necessary to play the game. With Super Dungeon Explore: Forgotten King – Upgrade Deck all expansions from the first edition may be used in the second edition. Several have also been re-released or re-packaged for the second edition. All new expansions are exclusively for the second edition.
Level boxes contain three heroes, one boss, one mini-boss, and three spawn points (one single and one double). This is enough for a "total conversion" of the base set, fielding three new heroes against three new spawn points and the new bosses.
Warbands contain one hero, one mini-boss, and two spawn points (two singles or one double). This also fits the requirements for each side in the official PvP Arena variant.
Tile sets contain six double-sided map tiles and a set of 12 creeps.
Boss boxes contain one boss figure, associated treasure and explore cards, and a set of 6 creeps.
Single boxes contain one or two models, usually a single hero or mini-boss, or a figure with cards to field as either (sometimes called a "dark hero").
