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.
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 experience and money
When lighting the candles in Mephisto's Realm, there is an area where you are supposed to throw the demon jumpers into the fire to lower the pedestal. If you stand by the edges of the level where the jumpers respawn, you can kill as many as desired. Try this as Spider-Man or any rapid fire projectile character. The enemies constantly drop money and energy refills. If one walks too far away, hopefully your teammates will chase after them and you can use the momentum move to wipe them out. Keep doing this for easy experience and money.
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.
Filler
While playing the game, quickly press Left, Right(2), Left, Up, Down(2), Up, Start. Your extreme attack will always be available with no energy cost.
Fourth alternate costume
Successfully complete the Combat Training challenge for a character to unlock his or her fourth costume.
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.

Recommended team
Use the following trick to make a hard to kill team. Create a team consisting of Wolverine, Blade, Luke Cage, and Ghost Rider (Bad To The Bone team). The team bonus will be that 5% of all damage will be regained as health. Also, all these characters have a way to regenerate health. Equip the following outfits. For Wolverine, Astonishing, max out Health Regen and Defense. For Blade, Ultimate, max out Health Regen and Defense. For Luke Cage, New Avengers, max out Health Regen and Defense. For Ghost Rider, Original, max out Resurrect Ally and Defense. It is also recommended that Ghost Rider be equipped with The Heart Of Mephisto (10% of attack damage turned into health) or a similar item because he is the only character without a Health Regen. Equip other characters with gear that increases defense or dodging capabilities. Not only will your team be difficult to hurt, but they will be absorbing and regenerating most of the damage they take. If a teammate dies, Ghost Rider will have about a 50% chance of resurrecting them. Note: Ghost Rider is the weak character. He does not regenerate, and if he dies resurrection is lost. Also, Wolverine will regenerate the fastest because he has an inherit ability to regenerate in addition to the suit's bonus.
For easy health, experience, energy, money, and Extreme Momentum Orbs for leveling, create a team consisting of Luke Cage, Elektra, and Dr.Strange. When they each have a full Momentum bar, get a group of enemies around you. Then, use the power. Elektra will stun all enemies with her Curse of the Hand. Then, Dr. Strange will use his Mystic Maelstrom to kill all stunned enemies, causing them to drop Extreme Momentum Orbs for each enemy killed. Luke Cage will use his Sweet Christmas to kill any of the remaining enemies, giving you +472% more money for each enemy killed in the attack sequence. This trick is especially useful for leveling characters, unlocking costumes, and maxing out stats. The best place to do this is in the Shield training simulator on the Thunderball mission. Even if you run out of time you will still get the levels and money; do not worry about killing the Boss. Just get your momentum on Luke Cage, Dr. Strange, and Elektra.
