After the beginning of the mission choose any flying character and fly to the right part of the location. Stand vis-a-vis to the glass wall and use Jean Grey's ability to take control over the man hidden on the other side. Then switch the computer on and return to your heroine - switch her into Magneto and break a blockade from the garage gate on the right.
Unlock the car and enter it. Follow the trace marked by studs to receive a minikit.
Stand in front to the wall on the right and choose Spider-Man. Pull out attachable points with your web and use Jean Grey to yank violet drawers on the left.
Now build a battery from the debris and charge it using Thor.
To receive this minikit, you must melt five gold pedestals with superheroes. Choose Human Torch and (on the second stage) head to the right. First target can be found near to the exit from this room.
Second is located on the other side of the same lift pit - in the room behind two blue-and-white walls.
Standing vis-a-vis to the locked gate turn right - next statuette can be found in the small room.
Open the gate mentioned before and enter the corridor. Next pedestal is standing on the right side.
The last statue is located in the room with Jarvis head. Look between two columns on the right side of the arena and melt your target.
Far before mentioned location go to the balustrade and choose any flying character. Fly up, so you can find a minikit hidden behind Jarvis red head.
In the room with strange, rotary machine (on the left from the blue-and-white wall) choose any big character and yank the door located on the first floor, using green handles.
In the room hidden behind the blue-and-white wall choose a character with a web attack and yank two attachable points hanged on the wall. Switch into Jean Grey and demolish violet shelves with her powers. Build a jukebox from the debris and pick up a minikit.
During final battle turn right and approach to the pool as Iceman. Freeze it and recover a minikit from the ice block.
During the same fight turn left, approaching to the locked door. Open it using Jean Grey's telekinetic abilities and pick up a minikit.
Turn to the left once more, so you can see a minikit floating above the abyss.
Kill Killian and wait for Mandarin to destroy all Iron Man's armors, so you can fly to the top floor of the building. Now switch into Magneto and break all three reflectors located on the balustrade.
