Conan, designed by Fred Henry and based on the Conan universe created by Robert E. Howard, is a scenario-based semi-cooperative asymmetric miniatures board game. One player is the Overlord, playing the opposition forces, and the other players (up to 4) play Conan and his companions: Shevatas the thief, Hadrathus the Priest/Sorcerer, Belit the pirate queen, Valeria the warrior, etc. The game is based purely on Robert E. Howard's novels and short stories (not the movies or other non-Howardian material). The publisher has hired Patrice Louinet, a Howard expert, to make sure the artwork and the scenarios are compatible with Howard's vision.

Each game is a scenario that is played on a map. There are 4 maps in the retail copy of the game, and each map can have several scenarios set on it. The game is fast, only one hour approximately. It's possible to play several scenarios in a campaign, but each scenario can also be played individually. The base box comes with 9 scenarios.

At the start of a scenario, players choose their team (Conan and two or three other heroes). The Overlord rounds up all the miniatures (picts, Necromancer, skeleton warriors, monsters, etc.), tokens, and cards from the chosen scenario. The game usually plays out in a limited number of turns (ten, for instance). Each scenario can have very different goals: find the princess captured by picts and hidden in a hut and leave the camp before the pict hunters return; find the magical key to open a sealed door, steal the jewel and leave; kill the Necromancer by the end of turn 10; survive by the end of turn 10; escape the prison; etc.

During their turn, heroes can activate or rest. If they activate, they may spend "gems" from their energy pool to do all sorts of actions: move, fight (melee or distance), defend, pick a lock, reroll, etc. If they rest, they may move a lot of gems from their "spent" pool box to their "available" pool box. When players take an action, they throw a number of dice equal to the number of gems they put in their action. There are three different kinds of dice in the game: yellow (the weaker dice), orange (medium) and red (strong). Each character has a color based on their specialty: Conan rolls red dice in combat while the Sorcerer rolls yellow dice in combat; the thief rolls red dice in Manipulation actions, while Conan rolls orange dice; etc. Each player can have equipment cards (armor, magic potions, weapons, etc.) which give them additional bonuses on their dice rolls.

The Overlord is played differently. The Overlord uses a board with eight slidable tiles, plus his own Energy gems. Each tile represents one unit (1 to 3 miniatures) on the game mat, and all of the miniature abilities are written on this tile (movement, armor, attack, special abilities). The tile position on the board corresponds to the numbers 1 through 8. The Overlord has a pool of energy gems and each time he activates one unit, he must spend a number of gems matching the tile placement: tile#1 costs 1 energy gem, tile#2 costs 2 gems, etc. Whatever tile the Overlord decides to activate, he spends the corresponding energy cost (moving his energy gems from the available pool to the spent pool), then takes the tile out and moves it to the end of the sliding track: If he wishes to activate this unit again, it will cost him 8 gems, because the unit is now on position 8. The Overlord can activate a maximum of two tiles, and he regains only a certain number of gems every turn (depending on the scenario).

In a typical scenario, the heroes must accomplish something and the Overlord wins if the heroes fail to reach their objective — but in some scenarios, the Overlord has his own objectives and the Heroes win if they prevent him from accomplishing his goal.
