Sand Central Station
Stan Lee can be rescued for the first time in the mission Sand Central Station.
After the fight with Abomination you will be transferred to the station - then choose Iron Man and fly to the balustrade on the left. Comic book writer can be found under the coffee machine - destroy it to release a poor man.
Times Square Off
At the end of the stage, but before the final fight with Doctor Octopus, fly to the silo located on the roof of the skyscraper. Use Iron Man's rockets to destroy all silver bricks and build a pump from the debris.
Switch to Jean Grey and use her telekinetic abilities to turn a violet valve. Stan Lee will be saved.
After a short play with the huge speaker you will be moved to the long corridor. Choose Magneto and lift up the metal box standing on the left. When the claw switch appears, use Wolverine's talons to unlock the mechanism - you will receive a minikit and rescue Stan Lee at the same time.
Rock Up at the Lock Up
In the first location fly up and head to the interior part of the building, steering to the left side. Destroy all boxes on the upper floor (behind the fence). Build iron bars from the debris and switch into Mr. Fantastic to pass through them.
On the other side choose Venom or Spider-Man and use spider sense to uncover attachable points. Yank them with your web to release Stan Lee.
In the second location go down and turn left. Switch into Sandman and use a sandbox to create a trampoline.
Red Head Detention
Enter to the factory part of the building (where you have met Human Torch for the first time) and fly up, heading to the upper-left corner of the room. Stan Lee is imprisoned in the strange blue machine - destroy it to rescue the writer.
In the observatory (first location) choose Iron Man and shoot your rockets at the silver shield in the central part of the area.
Warning! This location is available after the Bifrosty Reception mission, but before the Juggernauts and Crosses quest.
Stan Lee is surrounded by flames - approach to him as Jean Grey and take control over him. Use an old writer to build a device from the bricks. When it is done, return to the main character and turn violet valve with your telekinetic skills (interaction button). In that moment, all fires will be extinguished.
Juggernauts and Crosses
Go to the balcony of the X-Man school and turn right, heading to the burning box. Put all fires down using Iceman and then use some bricks to create green handles. Yank them using any big character to destroy the whole object.
Build a trampoline from the bricks, so Stan Lee can fall safely.
Doctor in the House
In the location, on which you must save Human Torch and Nick Fury, go to the right part of the castle, so you can see a cannon. Choose Spider-Man or Venom and use spider sense to uncover an attachable point. Yank it with your web, so you can arrange the right arc for the shot.
After that switch into Human Torch and fire a flame on the fuse.
That Sinking Feeling
Stan Lee can be rescued at the beginning of the stage - go to the upper floor on the right and switch into Magneto to move a metal box, under which the writer is lying.
Stan Lee can be found in the second laboratory. Stand between two rotating, electric machines, then fly up and head to the interior of the stage (as the rope in the middle shows). Land on the platform and shoot at the knocked writer to save him.
This time Stan Lee can be found in the location with aeroplane - poor man is surrounded by the flames. Extinguish the fire using Storm or Iceman and the problem will be solved.
Go to the huge, round hall with the galaxy visible behind the window and look upward. Fire Iron Man's rockets at the silver plate located in the centre of the ceiling to rescue Stan Lee.
A Doom With a View
This time Stan Lee can be rescued during the boss fight. Use claw switch on the right with Wolverine to unlock some bricks. Build a computer from them and hack it as Iron Man. That's all!
The Good, the Bad and the Hungry
Stan Lee can be saved during the last part of the fight with Galactus. Approach to the jet crushed on the left and switch into Sandman. Now just use sandbox to rescue an old writer.
