For those trying to get the medium badge, which I find harder than the hard badge! Some tips: The revolver is cool, but I found the ump overall better. You need people on your team, seriously it makes it much easier. The Hunting rifle is great, one hit ko to the head. I rocked the Hunting rifle chainsaw without glitch until I got the barrett, which you should absolutely shoot for, it's extremely powerful. Army Zombies you can kill faster through the legs, don't aim for their heads. Good Luck!
