Superman Returns: The Videogame Cheats (Xbox360)

The final tornado that threatens Metropolis is easy to figure out after a few tries. First
off when it appears, you have to save about 3 or 4 citizens in various places. Do that
first.

Then you have to go and put out a couple of building fires. Try using the SUPER DUPER
Breath.  One blow will snuff the fires. Then Superman will say something corny -- along
the lines of, "I have to try one more time". He'll automatically fly into the tornado and
here's where the encounter gets simple. 

When the tornado turns blue inside, use your heat vision and when the tornado turns red,
use your ice breath.

Pause thè game and press Y, Right, Y, Right, Up, Left, Right, Y.

Pause thè game and press Up(2), Down(2), Left, Right, Left, Right, Y, X.

You can find the cheat code on the Superman Returns DVD. At the menu, enter UP, RIGHT,
DOWN, RIGHT, UP, LEFT, DOWN, RIGHT, UP. Once entered, fly to the top of the GNN building.

Enter these cheats while in the Fortress of Solitude. To get there, hit BACK while in the
game to access the map, then press YELLOW to access the Fortress. "Supe R Man" cannot
access the fortress while there are enemies around, only when you're in free fly mode, so
go kick some ass.

Using cheats will not earn you any achievements while they are active (although one
achievement -- specifically for entering a cheat -- will unlock as soon as the first code
is entered). You still have to go out through the city and find your lost/hidden kittens
and mini-games.
