Jacinto Smoke Glitch Cheat for Gears of War 2 on the Xbox 360

Go right into the middle of the map at top end in Jacinto.

Then throw a smoke grenade down the steps onto the left crate.

Walk into the grenade before it explodes, and when you're down hold up and rapidly tap A.

When the camera angle changes get a friend to shoot you and you will be catapulted into the sky.

Tip: the more you press aim the higher into the sky you will go.
