While being alone is bad during zombie invasions, both for the mind and safety, making a moving fortress is bad in a big enough invasion unless you have an escape plan that isn't too far away. The zombies, while in a truck that big, would find you in no time with all the noise you are making. If I were out there silence would have to be my key force, keep my zombie encounter count down to a minimum, and when I do take them out with the weapons I listed earlier.

Yours is quite good for a sadistic kill fest escape, but if I had a greater choice I would pick something generally human to control, a hot air balloon, easy to navigate, easy to fuel, zombies can't fly, and it is silent enough that you won't get a big crowd following you until you land. Then stop off at the next elevated area, next town next understanding, and refuel.

I also would need to get myself out to sea, or find a pilot. I could navigate a small enough ship, but my voyage plan is quite long so I may need something big and maybe someone with more experience. And if I get a pilot and enough fuel then I can make the next wing of the trip rather easy.

Now I know a naval base, I have an air base in town. Both are good for me. I know someone with a hot air balloon, and if they are changed I'll just kill them. I also know an island my family owned by being islander royalty before we moved to America and decided to be poor. We still own it in case the world resurfaces to order, and it is off sea in a place where a zombie would enter the sea and get swept off in a current miles away, or broken on the rocks in a tsunami.

A big plan is good for international invasions(island hopper). Small ones for local invasions(Hot air escape). And a game plan for whatever may come(silence and keeping in shape).

Also to everyone who likes a flamethrower be warned, a flamethrower for the military lasted only a few seconds of fire if they had luck. So while burning a few zombies for those few seconds might be effective, now you have this big heavy backpack you wasted on these couple of guys and are weaponless. Also you are going to have to carry something big and heavy for fuel. If I were using fire I would be more akin to molotov cocktails. Get some highly flammable bits, mix them with something to make it gooey flammable bits, wrap the cloth AROUND the top of the bottle (learned that from one of my teachers who fought in Vietnam, said if you use in bottle release it will likely either fall out of the bottle, never ignite, or ignite in your hand.) lite and throw. Then my best advice is RUN. Because there is a good chance it will take them a while to die again since pain isn't happening and they are now a walking mass of fire. Though this seems very nice for a fortified area, if it is brick anyway. Toss it into the invading army, watch fifteen burnt, turn into twenty burnt, turn into forty burnt, and then a big wildfire of burning flesh.

But that's all for now, late.

I'd probably go all Resident Evil and pull out a few shotguns or something. How would I get those? Well, considering it's a zombie invasion, I doubt anyone is watching their weapons cabinets. I'd just raid one of them and start shooting at them. If anything, even if it didn't get them down, it would buy me some time to get out of the area because no matter what, a bullet wound would slow them down at least for a little while.

I'd also have to make sure I grabbed quite a bit of ammunition. Unlike in video games, there wouldn't be random boxes of 'munition laying around everywhere I looked... xD

When I suggested turning a truck into a makeshift tank, my mind was going to a simple 'plow through a horde into the clear' plan. A smaller vehicle, while excellent for a personal escape, would not allow you to take many others with you, especially if you have wounded, young, or elderly objectives to keep safe. It is noisy, but it is also relatively fast, and is capable of crossing a good deal of terrain. As you said, a lot would depend on the size of the outbreak, but my general plan in a larger event would be to use the truck to move us to an airport, where I would acquire an aircraft. I am not the best of pilots, generally local flights only, but I am confident that I could VFR myself and my passengers to a more secure location.

If I was just escaping by myself with no dependents, I would chose a dirt bike or a quad, and strap a couple of jerry cans on the back. Fast, nimble, capable of going anywhere, and easy on fuel. Unfortunately, as I mentioned before, they are not capable of carrying more than one (if that) passenger.

I think I'd whip around a lamp. Just 'cause it's there and it's metal.

Edit.

i would use portable chainsaw on one hand and a machete on the other.What a bloody mess would that be muhahaha

I pick a car. I can use it as a defensive and offensive weapon. Though windows would pose a problem. Oh well. Still, the idea is that they can't get in (easily anyway) and I can squish them with my mighty running machine.

I would also want a light, strong sword, with good reach, and as much body armor a I could possibly get my hands on. I don't don't DON'T want to be a zombie. And a sword doesn't require ammunition, so I won't get stuck asking the zombies to kindly stop advancing on me while I fumble around with another (insert name of ammunition here)

And it's not really a weapon, but a tactic for getting more weapons, I would definitely run down to the police station and ask them if I could stay there. I figure they'd be pretty willing to offer me asylum, and they'd be too distracted with a bunch of zombies to notice me sneaking off to the armory to steal all their interesting gear and weapons.


Edit: Now that I think of it, I don't know if I would approach the police station. It occurs to me they might shoot before they figure out I'm not a zombie. So I think I might just call 911 and ask them to come and get me, and then infiltrate their station and steal all their weapons.

A chainsaw 8)
