This is one of the harder achievements of this game. First off before you try to go for this achievement make sure you have a working controller plugged into your Xbox or you CANNOT get this achievement. Next step is to make sure your Xbox is ON, if for any reason it is not on pressing the power button on the console should turn it on. After that you're going to have to load up Shadows of the Damned. After a bit of loading it will ask you to press start then select a memory device that you'll use to save your game to, fortunately for this achievement any device you have will work, select any device by moving over to it using the left analog stick and confirm by pressing down on the A button (green one) After you do all this you'll get this 5g achievement. Good luck!
