For more information, see the DLC Expansion part of the trophy guide.
Additionally, even though the DLC has a separate list, the trophies are earned throughout the main game. There are no trophies glitches that I am aware of, but this is a port of an older game and the game itself can have random glitches. More importantly, Simulator missions are set to the difficulty you are playing on and I highly suggested you do them on Easy. Hard mode is challenging, even with characters carried over from a Normal run, so I recommend an extra playthrough on Easy despite adding some time to your quest for platinum. The way you want to approach the platinum is up to you, but this guide is written with the intent to get your platinum via the path of least resistance: three playthroughs.
The gameplay visuals have been improved a bit, but the cut-scenes are still less than desirable. Welcome to Marvel Ultimate Alliance, a dungeon-crawler RPG featuring the majority of Marvel’s finest that was originally released on the PS2 and PS3 in 2006, now ported to the PS4.
