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. Character specific gear are thus very valuable.

Note: Some of the codes may need to be used multiple times before they have any effect. Also, enabling codes by not allow achievements to be unlocked.

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, do some Versus mode missions with those characters to level them up, or to pick up some Shield Tokens to add to their costume.

Go to a S.H.E.I.L.D. save zone and select "Change Team". Delete all selected characters by pressing X. Once all of your team slots are empty, press Left(2), Right(2), Up, Down, Up, Down, Start. A sound will confirm correct code entry. Note: This code may also be enabled at the main menu.

Use Wolverine and have Lunge attack. It normally knocks down and opponent and slashes them, however because you are facing a Boss this will not happen. Keep using that attack and it will do more damage than melee attacks. It will not knock them back. When you run out of energy, the Boss should eventually produce some.

When lighting the candles in Mephisto's Realm, there is an area where you are meant to throw the demon jumpers into the fire to lower the pedestal. If you stand in 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 user. 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. Do this for easy experience and money.

Play the Galactus Boss battle. When he slams his fists and swipes at you, it does not hurt at all and you will get back up immediately. You are up on a ledge and his Punishers do not stop respawning. You can just grab and throw them off in either direction. To avoid being caught in his hand and button tapping, go on the left side of the screen on that corner.

The following 12 achievements require the Xbox 360 exclusive expansion.

Achievement	How to unlock
Archer Apparel ( 20 points )	Unlocked all the outfits for Hawkeye.
Creed's Cloth ( 20 points )	Unlocked all the outfits for Sabretooth.
Doom's Duds ( 20 points )	Unlocked all the outfits for Doom.
Doppelgänger ( 25 points )	Doom has spoken with himself.
Fleeting Allies ( 20 points )	Magneto has spoken to Xavier.
Gamma Garb ( 20 points )	Unlocked all the outfits for the Hulk.
Magnetic Regalia ( 20 points )	Unlocked all the outfits for Magneto.
Mutant Love ( 20 points )	Cyclops has spoken with Jean.
Optic Outfits ( 20 points )	Unlocked all the outfits for Cyclops.
Symbiote Skins ( 20 points )	Unlocked all the outfits for Venom.
Teleport Threads ( 20 points )	Unlocked all the outfits for Nightcrawler
Wrong Claws ( 25 points )	Sabretooth has been mistaken for Wolverine.

Complete the Combat Training challenge for a character. Alternately, get a "Bronze" rank in a character's Comic Mission to unlock his or her fourth costume.

Note: This trick requires downloadable content with the new characters. When the Hulk gains Fury (the move that makes him bigger), use it and grab a weapon. Drop the weapon and pick it up again. It should be bigger. It will still function like a normal weapon. The only weapon with a size limit is the mace (about five times).

Characters that require Xbox Live to be unlocked may also be obtained on Marvel: Ultimate Alliance Gold Edition. It includes characters such as Cyclops, Magneto, Hulk, Venom, Dr. Doom, Hawkeye, Nightcrawler, and Sabretooth. This is useful if you do not have Xbox Live.

Successfully complete the game under the normal 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 one maxed out in normal mode, there is even more room for improvement.

After the third level, go to Iron Man's lab and talk to Spider-Man. He will say "The only thing that could make this worse is if Earth was blown up to make an intergalactic highway".

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 sit back and hit him with your ranged attacks. Then when needed, fly in and collect the health and energy vials he drops.

Have Deadpool on your team. When you find a door that does not give you the option "Press X to open". Sometimes you can use Deadpool to teleport through the door. Once through the door, just continue walking with Deadpool for awhile and your team will catch up with you. This also works on doors you would otherwise have to break. A notable time this does not work is in Murderworld (the doors that need the hammer and strength machine to open). It does however allow you to go one-on-one with Shocker and Rhino in the pinball machine. Your team does not pass through the door with you in this instance.

Use the following trick to make a hard to kill team. Make a team consisting of Wolverine, Blade, Ghost Rider, and Luke Cage (the Bad To the Bone team). The team bonus will be that 5% of all damage will regained as health. Also, all these characters have a way to regenerate health. Equip he 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 a 50% chance of resurrecting them. Note that Ghost Rider is the weak point. 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 money, health, energy, Extreme Momentum Orbs, and experience for leveling. make 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 uses his Mystic Maelstrom to kill all stunned enemies, causing them to drop Extreme Momentum Orbs for each enemy killed. Then, Luke Cage uses 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.

Some achievements cannot be unlocked after certain cheat codes are activated. Use the following trick to get those achievement points available to you again. Make a new profile on your Xbox 360 then start a new game. This profile has no saved content and therefore will not have cheats on it. After starting a new game, sign in the profile that has been locked from achievements and join in. You will now be able to start from the beginning and play with your default profile. If you are alone, just have two controllers. From here, simply play until you get to an extraction point. Save with your blocked profile. Start a new game with your previously blocked profile. You can now start over.

Gain between two and four levels with a character. Alternately, defeat 30 enemies with a character to unlock his or her second costume. Defeat 175 enemies with a character to unlock his or her second costume.

Additionally, there are 25 secret achievements.

During the missions is Asgard you may talk to Weasle after completing one of the two missions available. Weasle will be in the Hall of Heroes. After he talks to you, talk to him by pressing X. When you ask him about the Ex mansion, the subtitle reads "Makes me wish I was a mutant. They've got everything here - tennis courts, a pool, and a subbasement full of hi-tech gear" however the voice artist clearly says "They've got everything there", which would be the correct way to say it.
