Hard mode
Successfully complete the game on the Normal difficulty setting to unlock the Hard difficulty setting. Do not be afraid of the Hard difficulty setting. When you start a game under Hard mode, you can load your characters from a previously saved game. For example, if you have a level 50 Wolverine from Normal mode, you can start the game with him and all his powers, gear, and costumes that you have gained. It also adds five more dots to level up your powers with. If you have a character maxed out in Normal mode, there is even more room for improvement.

Easy Comic missions
To complete all the Comic missions easily and unlock Silver Surfer and get gold at the same time, wait and play all the missions at the end of the game when your characters have leveled up and have decent powers. If some are still to difficult to complete, play some Versus mode missions with those characters to level them up and/or pick up some Shield Tokens to add to their costume.

Easy Iron Man Comic mission
When you get to the end of the mission to battle Ultimo, run back to the door you came in. Ultimo is so big he cannot pass the edge of the room he is in. You can just keep hitting him with your ranged attacks, then when needed, fly in and collect the health and energy vials he drops.

Character specific items
Character specific gear is very valuable. When picking up character specific items, such as "Iron Man's Coil", it is described as doing +3 Damage and +3 Rocket Uppercut. This is not +3 to damage for the hit; it means that it adds three dots in the Powers area. With this single item you can go from 129 Damage to 289 Damage.
