Stand on a Shield Cheat for Gears of War 2 on the Xbox 360

On any map that has stairs look at the bottom of the stairs and you will see 2 lines.

Plant a shield on the bottom line (facing away from the stairs), then go up to it and you should go on top of it .

Then get another shield and put it a few inches away from the other shield (like 1, 2 or 3), then get back to the shield where you can jump over and it should work.
