Iron Man Cheats and Tips

When you get to the flying fotress level and you are up to the canon. Stand on the glass above the canon and punch. You will blow it up without a scratch. Hope it helped this was my first cheat.

You have to go above the central building and just kill every bad guy you can see as fast as you can (it may take a few tries) then you have to blow up all the missiles before they hit the ground. Once the gate to the building opens up (it will be on your radar) you have to go inside and take out the machine. It only takes about three hits. Once you do that, the level is over.

If you shoot at the heads that are shooting at you, you will be able to break them
