In Vs. System 2PCG; players choose a main character; build a deck with exactly sixty cards; and attempt to stun the other player's main character in a game of superhero battle. The first set — Vs System 2PCG: The Marvel Battles — contains characters only from the Marvel Universe; but future sets may add other IPs.Vs System 2PCG: The Marvel Battles is superficially similar to the original Vs. System collectible card game; but is a completely rebuilt game that takes some inspiration from the original. Combat has been streamlined; the turn structure is different; the resource system has been revamped; and the game is no longer collectible; with cards instead being released in a non-random format. A single box contains a full play-set of all cards.
