Build the deck you want from your card collection, or use an automatic deck builder to make new decks to play with. Collect crafting items to create "potions" for temporary character modifications in the interactive game worlds, craft sidekicks for the characters, upgrades for sidekicks, or even whole characters. Most activities - missions, card game, interacting with game world environment reward players with prizes and/or game currency called fractals, after a main storyline of the Super Hero Squad Show. The currency is used to buy new heroes, unlock highest levels for heroes, buy sidekicks, HQ rooms and objects, goodies for your heroes, mystery boxes, missions, cards and "card quests". A major update on June 26, 2014 replaced a prize wheel and the original currency system with a new system. The previous challenge system was replaced with a new achievement system for further ways to earn in-game rewards. That update also switched the starting characters for players from Cyclops, Falcon, Ms. Marvel and Thing to Black Widow, Hulk, Iron Man and Spider-man.
