Sentinels of the Multiverse is a cooperative, tabletop multiplayer card game where the players are superheroes fighting one or more villains in a changing environment. The video game version just released multiplayer support and is on sale this weekend on Steam and other places, with some of the money being donated to the Child’s Play charity.
The game has a distinctive art style and a certain amount of flavor. The rules appear to be simple, but there’s significant replayability. Players I’ve known who like the game really, really like it (I’m one!).
