Anyone not spending the extra $1 for the AR15 upgrade from the Glock is nuts. With glock you aren't hitting zombies in the head further out than like 20 yards, or at least I can't. With AR, I get range and close quarters.
Also I don't know what and ABC warrior is
Don't need any of that if you got an ABC Warrior.
Now that I have thought about it, the only change I may make is that upgrade.
The swarm nature of zombies implies that the ABC Warrior may be overwhelmed at a critical moment.
My rationale was that I wanted everyone in my party to have something to defend themselves with.
But the use cases for a pocket knife against zombies are narrow. You will most likely find a jagged piece of metal laying around that would be just as useful as a pocket knife. I would probably make that upgrade.
I think that you have to keep the luxury apartment. You could demolish a few floors below, so that the only means to reach the penthouse is a rope or a ladder. I've never seen a zombie climb a rope.
We are assuming here that the luxury apartment has clean running water. If it does not, you may have to go with a villa by a lake. The reason why you don't want any of the options other than the luxury apartment is that they are all relatively ground level. At ground level, even with the ABC Warrior, you won't last long when waves of zombies are descending upon you at all angles deep into the night while you are sound asleep.
I went with the tv dinner because I think that you have to. So now, in addition to the clean water, the luxury apartments also has to have refrigeration capabilities to keep the tv dinners frozen.
Think about it.
Let's say that you impregnate your lady. You're going to feed your baby beans?
You have the penthouse luxury apartment. You have clean running water and a freezer to store your food (because I said so, that's why). You have a choke point that zombies are not known to traverse.
At this point, you only have to worry about scavengers. If you have an ABC Warrior hunkered down, protecting the choke point, scavengers are going to think twice before scaling whatever obstacles I have erected. I would place that ABC Warrior in a position that would make it very challenging to disable, because disabling the ABC Warrior is the scavengers only chance.
