Complete a Marked Map Destination Using Only Firearms
Just like completing a marked destination only using the crossbow, just using firearms is just as it sounds--you cannot use anything but bullets to kill walkers. This means if you get grabbed you must let the walker kill you as the stabbing with the hunting knife counts as a knife kill. Some levels are of course easier than others, although getting one kill with a gun and then running through the rest of a missions is always a viable option.
