Sentinels of the Multiverse is a cooperative, fixed-deck card game with a comic book flavor. Each player plays as one of ten heroes, against one of four villains, and the battle takes place in one of four different dynamic environments.
Each player, after selecting one of the heroes, plays a deck of 40 cards against the villain and environment decks, which "play themselves", requiring the players to put the top card of the appropriate deck into play on the villain and environment turns. On each player’s turn, they may play a card from their hand, use a power printed on one of their cards in play, and draw a card from their deck. Each round starts with the villain turn, continues clockwise around the table, then concludes with the environment turn. Each villain has various advantages, such as starting with certain cards in play, as specified by the villain character card. Play continues until the heroes reduce the villain to 0 or fewer HP, or until the villain defeats the heroes, either via a win condition or by reducing all the heroes to 0 or fewer HP.
