Bioshock Infinite - A Real Pistol - Farming Method
Please see video below for more details but what you need to do is collect the pistol (just before you step up on the boat). then go ahead and kill as many people as you can see and then restart checkpoint because your kills dont reset. This way you have time to focus more on collectibles ETC ETC
