Ok so first things act 1 the tutorial levels if u really dont think ur up to the challenge just go easy heli level is easy so u dont need to know most important is to do all the subquests in stark tower my featured team was Spidey(my fav)
Human torch,iron man and iceman just for back up i figured that was a beginners team since iceman can boost ur attacks with his moves and spidey is just good for ranging(web bullets)iron man is the strength and human torch is the artilary now at act 2 in Dr.Stranges house go into the good docters room with Dr.strange(u get him in the end of act 1)
and pick up the focus upgrades then go upstairs and get the book and daredevil doll(optional) now fighting blackheart and Mephisto isnt easy(well black heart is) but mephisto has a god mode to normal supoerhero moves finishers even normal attacks so u must locate the sword and weaken him(hit him 3~4 times only or he'll get his health back)then break a statue then disarm him and use the sword to break another statue until all of em are gone then the rest is easy for act 3 which is asgard home of thor u will have to beat the destroyer armore which is supposed to be invincable to any attacks go find loki which is surrounded in ice(not breakable)and hit the robot which will make him use his lasers step behind loki and it will hit him they will both go out(easy as pie)then step outside and ull see doom(which will kill u all!!!! )nah just kiddin ull get warped in the knik of time by the watcher now my little act 4 hints hehe u should be atlease lvl 25 now(if u did the trivia too)so use deadpool's finisher to take out a large armount of enemys at once.Well thats the end of this comment when u would like to and play safely(dont go overtime on it)
hope u beat the game get all the characters and find all the comic missions hehehe im crazy(haha just kiddin)
