Repeated Reloads Cheat for Gears of War 2 on the Xbox 360

To do this you need to use a Lancer.

You reload (not manualy, your ammo must run out) then rev the chainsaw and when the cartridge falls your player will start to put another in.

Rev the chainsaw and it will also fall, then repeat the process and they will start to pile up and never stop falling (this will not make you lose additional ammo).
