Instructions
Press the assigned button that you see flashing on the screen when you take control of Banner after the cutscene. By pressing the button, you will break through the rubble in front of you and will turn into the Hulk.
With your fists, break the door down in the room that you enter. Defeat the enemies on the other side with your fists as well. As you fight, an objective will appear that tells you to defeat the Army forces. Jump the wall and fight more enemies, and then head towards the exit in the back right corner.
Find the room with a large hole in the ceiling. A helicopter will come through the hole. You must locate a large object and throw it at the helicopter. If you hit the helicopter and destroy it, you will move on to the boss fight for the level.
Defeat Blonsky and his men in the boss fight. You will be fighting Blonsky, two armored suits and two men. Go for Blonsky first. His health meter is in the top-left corner of your screen. Once he is defeated, go after the armored suits. Once you have beaten them, go after the two men. Once you have defeated all of the enemies, the Hulk will be placed in New York City for the next level.
