How do you get the Cluckshot in Gears of war 3 Campaign

ONLY FOR X BOX 360......... WELL ONLY THIS WAY IS......... You can only receive cluckshot in Act 4 of the campaign... well to my knowledge. i have heard rumors of it being in the first act but i have yet to explore that. Anyway, in order to get the cluckshot, you must start Act 4 of the Gears of war 3 campaign on INSANE difficulty! Then as you walk through the town, be sure ABSOLUTELY sure not to bump, crash or shoot any of the dust statue. This will not only get you an achievement but also you cant get the cluckshot without it. Then when you get the the tower, the snitch trying to kill you will actually let you up... after a threat from Marcus of Course.... LOL. anyway, then follow him until you find an armory. it should be on your left, and the armory will have metal bars like a jail cell in the doorway. if you didn't kill any of the dust statues, the person will let you in. go to the right and you will find a chicken with I believe a Pirate Hat on it. Go up to it and click X (feel free to take the weapon ammo there too ;). then as you navigate through the rest of the chapter in Act four, be care full to find ammo boxes. There will be three ammo boxes that you must get in order to get your cluckshot. One is on a car about to fall of a cliff. Approach it and hit X. The car will fall, that is what you want to happen! Then there will be one on a train track that is hanging over a ledge, hit X. That will fall too... that is what you want to happen also. The final one will be on three or so boxes near an edge. Approach it and hit X. It will also fall... but rise with a reward! your cluckshot! If you did all the right things, a chicken with a Pirate Hat will be riding the three ammo boxes that you made fall. It will act like a drop ship and drop four Cluckshots that shoot exploding chickens!!! it is a fun and easy Easter Egg! ENJOY!!!
