2. General hints and tips
Marvel: Ultimate Alliance can be completed over Xbox Live or locally. I recommend completing it locally, unless you can find a group of reliable co-op partners.
This game is not a quick adventure. Additionally, it can be a somewhat frustrating experience on the hardest difficulty. Keep in mind, however, that you can return to previous S.H.I.E.L.D. checkpoints in order to defeat basic enemies, which will help you level up.
Do not play any sim missions until after you have defeated Dr. Doom. This prevents costumes from locking and glitching to prevent you from getting the achievement for unlocking every costume for every hero (Non-DLC).
