Chicken Hat is an item in Metal Gear Solid 5: The Phantom Pain. It looks like a chicken’s head wrapped around your own, and makes the game easier to play.'; document.getElementById("serge_648ac998c20ba86b43957c42").style.display = "block"; }

The hat is available right from the start. You have to enable it from the game menu: Main Menu -> Game Settings. If you fail a mission several times, the game will offer you to turn it on. There’s no way to wear it without affecting the game, sadly.
