Quoted from musketd:
I fealt the same way you did about the audio until; I played it. The audio is great. Hulk sounds awesome and so do the other Avengers too; the only one thats sounds off is nick fury, but even if they used the same people to do the voices as xmen the call outs are done better on Avengers for sure. Like I said I think when you play it; you will have no more gripes about the voices.
ps LOKI's voice is well badazz
Wait! You mean Gerry should actually play the game and listen to the audio before complaining about how bad it is??
