Farming Simulator this isn't. The Culling of the Cows is a gory, amusing zombie cow massacre with tower defense elements. As crotchety and slightly delirious rancher Sammy you must mow down the bovine menace with upgradeable weapons and shame them with fierce put-downs. Watch out for the UFOs and be sure to hold your nukes back for the big bad guys.
We have 500,000 Steam Keys for the game to give away. At $12.99 each, that's six and a half million bucks worth of free games. All you have to do to grab a key is follow the instructions in the widget below.
We're giving away these keys in association with Bundle Stars, who are currently running a May Madness sale with a huge number of Steam bundles on sale, including the Shadow of Mordor Bundle, which includes the game and all DLC for $19.99 / £11.99.
