Update 1.2 adds the Heroic and Super Heroic difficulty modes for all heroes. Players who defeat Dr. Doom or reach level 30 can access Heroic mode; Dr. Doom must be defeated in Heroic (or players must reach level 45) before Super Heroic is made available. Both modes offer new loot and enemies to match the increased difficulty.
Also new to the game are relics, which offer special stat boosts to heroes as well unique items that are as powerful as they are rare. Finally, Emma Frost is now a playable character, providing new powers like mind control and Diamond Form tanking. She can be purchased individually or through a special hero pack.
