You don't need a kit, you need training. Everything is a fucking weapon, and the sooner you realize that the longer you'll live. The only thing you need for zombie survival is one part awesome, one part badass, and two parts pissed off.
Oh yeah? What kind of training would you recommend?
firearms training and general fitness training would be a good start. survival training is a necessity as far as living off the land goes because if zombies do come you would be stupid to keep in the city. fixing and maintaining simple or even more complicated machines and electronics such as radios, engines, wells if you find a property that has one. so on and so forth.
zombie survival kits have more than just weapons. weapons are the most common part of it though of but they also require watter, food, first aid kit, tools, so on and so forth.
just sayin
