Marvel: Ultimate Alliance

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.

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.

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.

Successfully complete the game on the Normal difficulty setting to unlock the Hard difficulty setting.

Beat the game on Normal Mode.

Okay, the way I have a very hard to beat team is:

First use the 'All Characters' cheat.Then pick Ghost Rider. Level up his Penant Stare, Flechette Chain, and Damnation as much as possible. Next, you pick Doctor Strange. Level Up whatever you want on him. Next is Silver Surfer. Make sure you level up his 'Molecular Mix-up' and basic energy beam. Lastly, pick Spider-Man. Level up any long-range attacks from him. Those are good. I beat the game seven times in one day with this team.

When mandrin has gone up in is teleport pad and released the spder bombs get a flying character. Hover over the correct teleport pad. The spiders will go under you and teleport into the room and blow up the ultimos so you can go on the teleport pad and attack mandrin.

In Mephisto's Realm in the beginning area with the alter that reads, "Thy way shall be lit by the flames of impure souls." you can garner huge amounts of XP (infinite, if you wish) in a very short amount of time. Where the demons spawn, they will instantly respawn after every death. This is the fastest respawn rate that I've run across in the game (much faster than the Omega Base simulation missions' infinite spawn room or the Asgard simulation area). The demons respawn so quickly, that throwing attacks that return (Thor's hammer throw, DD's Extensive Strike for example) can actually kill one on the way out and one on the way back.

If your heroes are capable of quickly killing (one or two attacks) these low HP mobs , you will rapidly level all of your heroes or get costumes of heroes you don't already have. Thor's Mjolnir's Might or Dare Devil's ES seem perfect for this and only get better as you quickly level. Alternatively, you could throw the demons over the edge (*not* into the lava in the center, or the portal will open and the mission is over) but it isn't very quick. There is no need to worry about mana expensive, the blue orbs start popping so quickly that soon all of the orbs are just adding to the XP.

After a very short period of time, you will start seeing full-momentum orbs start to pop out too, which means that you can start using your Extreme attacks on a regular basis. Rising 16 levels in less than a 30 minutes is probably very doable.
