I'll pull out my katana and slice its head off.
I'm not a fan of guns on zombies, unless you're using a shotgun (big holes close range!

) because most bullets don't do anything to them unless you hit them in the head, and I have horrible aim, so traditional weaponry will be the way to go. Sure, it's short range, but if you're constantly slicing heads off, you have no problem. And you never run out of ammo

First thing after weapons, (or maybe before) is to get a decent vehicle, in case you need to make a fast getaway.
I'd also try and find any survivors, because, hey, two, three, four, five, etc is better than one...except in the case of zombies.
Flashy things are also good. Fireworks.
~I'll add more later, I need to go to school now. =D I like this thread
