Guide Lego Iron Man 2 [Android]

You will start on the ramp up to the road that surrounds Grand Central Station. Clear a path up the ramp by smashing the taxis with Hulk. In front of the bus, use Iron Man's explosives to break the caps off of the fire hydrants to erode the sand blocking the bus, then use Hulk to smash the sand out of the way and remove the bus. Clear away some more taxis with Hulk, then blow out the side of the tanker truck with Iron Man's explosives to reveal some LEGO pieces. Assemble the pieces into handles so that Hulk can remove the truck.

Use Hulk to throw the piece of junk on the left at one of the sand hands, then use Iron Man's explosives to get rid of the turnstiles on the right, revealing another object for Hulk to throw at the other sand hand. A sand train will arrive to block your path. Defeat 25 sand passengers to proceed.
In order to remove the wall blocking your path, you must first weaken it by blasting it with water from the giant water gun that can be built from pieces obtained by blowing up the silver globe on top of the information booth. One the wall has been weakened, smash it with Hulk
To destroy the wall with sand guns on top of it, use Iron Man's explosives to destroy the scaffolding on the right, then build the pieces int an anvil,
You will be joined by Spider-Man.
Use Hulk to clear away the fallen letters, then use Iron Man's explosives to get rid of the metal fence on the left. Use Spider-Man's Spider Sense to find an attachment point, then yank it to destroy the generator. Use Spider Sense again on the right to find a way to climb up the wall, then find an attachment point and yank to pull down a satellite dish. Build the pieces into a device that will destroy the second generator, once pulled by Hulk. Once both generators are destroyed, use Spider Sense again to find two attachment points on the giant letter A, then yank them to pull the A over, creating a ramp up to the next section of roof.
To reach this level, you must skydive off of the Shield Helicarrier and land in the park below. Once on the ground, head to the gate and smash the streetlight. Build its pieces into a grate that Mr. Fantastic can squeeze through. On the other side, smash the blue satellite dish, then build its pieces into a transformation pad for Mr. Fantastic. Use it to open the gate and let Captain America out. Deal with all the Octobots around where you start. Once you have done that, more Octobots will burst through the wall, creating pieces for a Fantastic 4 pad. Build the pad, then stretch Mr. Fantastic into a screwdriver to remove the bars covering the Shield Switch. Activate the switch, turning on the elevator to the second level. Going up to the second level will scare off Doc Ock, who will wreck the place and set it on fire on his way out. Equip Captain America's Shield and walk through the fire to the left half of the area. Use the pieces Doc Ock created when he left to build a Grate Portal, and take Mr. Fantastic over to join Captain America. Once there, have Mr. Fantastic rip open the wall using the attachment point, creating pieces that can be build into a Shield Switch. Activate the switch, then use the computer terminal (up the ladder) to plug in the ray gun. Hop on the red button to turn it on.
