Guacamelee! Super Turbo Championship Edition had Steam trading card support added on August 21, 2014. There are 8 cards in the series, and you'll receive 4 cards at random for purchasing and playing the game.
This game is an enhanced version of Guacamelee! Gold Edition, which also has trading card support. The two card sets, however, are separate - you won't receive cards from the gold edition set by purchasing this version of the game.
Note: The foil badge had a new picture version to replace the previous foil badge, which was ULTIMATE INTENSOOOOOOOO!!!.
