Players will choose between two factions – Heroes or Heralds– and will engage in a series of battles with the opposing side to help save the world or take it over. Gameplay in the Heroes & Heralds mode will be altered through the acquisition of Ability cards that range from basic alterations (speed boost) to game-changing, combo enhancing powers (invisibility or ability to pass through projectiles). Cards can be used in online and offline versions of the Heroes & Heralds modes as well as the training mode. Ability cards are based on classic Marvel and Capcom characters.
