Marvel Heroes launched Game Update 2.3, also known as Training Day. This latest update introduced an all-new game mode for players to enjoy. The S.H.I.E.L.D Holo-Sim game mode lets players dive into a high-tech holographic simulation room either alone or with a friend and face waves of enemies and iconic villains; the more waves of enemies defeated, the better the reward.
The update also includes design reviews for both Human Torch and Daredevil (the latter of which also got a snazzy new Noir costume) as well as item, crafting, and loot changes. Full details can be found in the Training Day patch notes.
