Not necessarily something on a global scale, nor at the level of a small Romanian village of infected people. A large city with a population of a million sounds about right. Yeah. With a few small pockets of non-infected. Maybe five or so groups of six. I could totally lead one of those packs. We'd be the badass pack.
Damn, that would be so awesome.
If I ever found a magic lamp, that would probably be my one wish, a zombie outbreak. Or if there was some crazy make-a-cancer-nerd-wish-foundation, that would be what I'd ask for.
Also, I guarantee you if I ever find myself in some cool government lab, with stainless steel doors and weird automated robot arms, and if I see some freaky vials with green or blue stuff inside... I guarantee you I'll take it. Then I'd gather all my armaments before breaking said vials directly in the center of the city.
Just awesome.
Look at my inbox fill up already... Ryan, you're nuts... Ryan what are you thinking?... Have you lost your mind?! A zombie outbreak?? What if my friend becomes a zombie and I have to blow his brains out with a high-power assault rifle?... What about the sociological/economical/ecological ramifications?
All these questions, and yet they beg one answer: because it would be awwwwwwesome. Send. Message sent.
C'mon... ah... there you go... there's that smile. You're thinking about how awesome it would be to walk around an empty city with four of your closest pals, looting all the cool stores and bashing zombie heads in. And just to be clear, we're talking slow-ass Romero zombies, not those terrifying fast-ass remake zombies. Krishna zombies. Blue paint zombies. If none of this appeals to you then let's face it, you don't know how to have fun.
This has nothing to do with the recent zombie appreciation trend. City-wide zombie walks in June.
Anime zombie cartoon super happy fun times. Zombie Elvis. Zombie Jesus. Well... that one kind of makes sense. But hell, I even saw a book the other day, Pride & Prejudice & Zombies. This is all fine and great and exploitative and all, but when that day comes, that fateful Z-Day, your trinkets and funny books ain't gonna cut it.
You have to be prepared.
Are you prepared? You better get prepared, because zombie outbreaks tend to lose their fun if one happens and you're merely pared. Pre. Means do it now.
Before the zombies. Let the good times roll, right?
Right.
Oh man.
Sure there's books and survival guides and manuals and seminars and all this mumbo jumbo that you could buy into like all the regular chumps, but ultimately the only thing that's going to keep you alive is your ability to stay focused, maintain your desire to beat the hell out of a ton of undead bastards, and your choice of weaponry.

In the game of re-killing zombies, weaponry could be the most important detail when it comes to your survival, and ultimate enjoyment of the outbreak. There are so many factors one needs to evaluate: weight of the weapon, dependency on ammo, type of ammo, range of fire, spray radius... you see, you can't just assume that the seemingly efficient handgun can get you through the day, nor can you rely solely on a fully automatic bullet-sprayer.
Every and any weapon is a valuable one, but understanding when and where to use them is critical.
I've spent a lot of time going over scenarios and writing long equations, extrapolating, punching numbers into the Eliminatulon LX, that sort of thing, and I think I've nailed the perfect weapons.

Firstly, the shotgun. I think of this as the last resort, backed in a corner, partially accepted your demise type of weapon. Under relaxed circumstances however, this firearm is not only incredibly
badass, but fun. It's moderately cumbersome, doesn't hold much ammo and is a bigger pain to reload than say a small semi-automatic gun, but this baby can do some damage.
And with a spray of smaller bits and pieces, you can maximize your offense and even take out multiple walkers in close proximity. Did I mention it looks super
badass to fire? Get yourself caught short though and your back teeth will be en route through your ex-best friend's colon.

My second pick is kind of a dark horse, and definitely not the most sensible of weapons... in fact... it's completely stupid in terms of logistics and survival. This pick is entirely from the video-game section of my brain. That weapon... twin knuckle dusters. Mark my words: there is nothing... NOTHING...
badassier than a dude (me) destroying zombie heads by punching right through them. With your fists. Imagine running through an abandoned mall, with nothing but brass knuckles, caving in faces by the handful. You can't buy awesome like that. Unless you can afford two of those zombie maker juice vials.

My last pick is another unorthodox choice for zombie offence/defense, but one that serves as a merger between the sensibility and functionality of a firearm, and the fun and sport of
annihilating the living dead. This particular weapon has been ruining people's shit for centuries, and if I had my way I'd be messing up a zombie's day with it too.
It was good enough for Bruce Wayne. It was good enough for Bruce Willis.
It was even good enough for Ghost Dog.
I'm
talkin 'bout the samurai sword.
Oh baby. I bet you wish you thought of that. Think about it, it's the perfect weapon. You can impale with it. Slice with it. Separate stuff with it. Horizontal. Vertical. But even better, diagonal. I'd be cutting every zombie diagonally. A thousand diagonal cuts per day, my god. When I got really good at slicing zombies (which I would), I would wait out in the middle of the street until a small group of undead formed around me. Then I'd super-slice the lot of them - diagonally - and stand back and watch all the zombie wedges slowly slide to the ground - diagonally.
I would trade Christmases forever for one weekend zombie outbreak.
Ninja kicks. Uppercuts. Falcon punches. Heart punches. The possibilities are endless. Can you imagine?
A boy can dream, I guess. And until the day that I can lovingly force a bullet into the medulla oblongata of a corpse thought dead, I will continue to dream that dream.
I will also continue to not wash my hands after using filthy bathrooms and then ride public transit. I will also be more liberal with my high-fives. Basically, I will do anything it takes to expedite the whole zombie outbreak process.
I'm keeping the dream alive, and you should too.
Oh, and don't worry... when that day comes, and you've turned... I promise I will have no problem taking you out with a shotgun or super-punch or diagonal slice.
