There are several things you need if you are going to survive a zombie apocalypse. Some of these things include water, food, medication, a first aid kit, hygienic tools (such as soap, towels, shampoo, and toilet paper), utility supplies (including batteries, knife, can opener, torches, and matches). Some other items of interest include phone, keys, enough gas in the car, and possibly a tent. Last, but not least, the most significant item which will ensure survival is a weapon.
Rifles or shotguns tend to be the weapons of choice. However, knives, axes, machetes, shovels, and baseball bats are also useful. You should also ensure that you have identified a safe meeting area and the easiest route to get there. Make sure to locate the closest hospital, gas station, grocery stores, and banks. It is also imperative that you know every exit out of your town and the fastest way there. Also, keep calm and have a map handy.
