Dune: Imperium uses deck-building to add a hidden-information angle to traditional worker placement.
You start with a unique leader card, as well as a deck identical to those of your opponents. As you acquire cards and build your deck, your choices will define your strengths and weaknesses. Cards allow you to send your Agents to certain spaces on the game board, so how your deck evolves affects your strategy. You might become more powerful militarily, able to deploy more troops than your opponents. Or you might acquire cards that give you an edge with the four political factions represented in the game: the Emperor, the Spacing Guild, the Bene Gesserit, and the Fremen.

Unlike many deck-building games, you don’t play your entire hand in one turn. Instead, you draw a hand of cards at the start of every round and alternate with other players, taking one Agent turn at a time (playing one card to send one of your Agents to the game board). When it’s your turn and you have no more Agents to place, you’ll take a Reveal turn, revealing the rest of your cards, which will provide Persuasion and Swords. Persuasion is used to acquire more cards, and Swords help your troops fight for the current round’s rewards as shown on the revealed Conflict card.
