-Obtain the nessecary supplies and weapons to stay alive. Non perishable food items, those that can't spoil, water, anything else. Also, gather as much gasoline as possible for the following steps. Find gun stores and gather as many weapons as possible.
You will definitely need supplies to save yourself from the zombie invasion, you'll need butt loads of gas to keep a vehicle running for a long time, and you'll need weapons. Not just guns. You'll need melee weapons. Bats. Hammers. Wrenches. Anything that'll keep the undead away from you.
