Vs. System
Vs. System (short for Versus System), also written as VS System and abbreviated as VS, is a collectible card game (CCG) designed by Upper Deck Entertainment (UDE). In the game, players build and play a deck of Vs. System cards in an attempt to win a game against their opponent. It was first published in 2004 and is set in the superhero genre. The game was discontinued by Upper Deck Entertainment in January 2009. It was announced at the 2014 Gen Con Indianapolis that UDE would be testing the crowd with a reprinted subset of Marvel Origins, as "Vs. System Living Card Game".
It has been recently announced (12/2/2014) that UDE will be relaunching VS System at the 2015 Gen Con Indianapolis.
Superheroic setting
The sets of the Vs. System are based on the superheroic settings of Marvel and DC Comics, with the exception of a smaller set called the Hellboy Essential Collection. For the most part expansion sets alternated release between Marvel based sets and DC Comics based sets with new sets every three to six months. All sets are interchangeable and compatible with each other and share the same card back. This allows players to mix characters fighting against or with each other.
