cats.jpg?t=1363741096 Have you added any Workshop items to your game? If not, time to do it. The creative modders of L4D2 continue to add new content every day. The Cat mod pictured above changes all the common infected into cats. Do you shoot them or do you hug them? A little tip, hugging will not end well and shooting them is really, really hard. To download and keep your cats and other mods up to date, just click the subscribe button on the item page. Next time you start the game you will see the game automatically downloading the custom content.
