I kinda made story about something like this awhile back in high school. except it was more of a post gobal war setting. considering that Zombies coming out of the ground isnt exactly reality but rather a virus like the one in 28 Days Later and I AM LEGEND. A virus is more likely to happen in reality to cause such a thing.. so i'd go with that kind of zombie attacked world where they're everywhere and hiding in the dark.
My weapons
considering i did study japanese sword fighting, i'd take both my daitos or at least one of them for close combat like in a building, but thats not to say i wouldn't have a pistol. probably a Springfield 1911 with silencer. remember a blade is a good idea considering that the gun could run out and then your f**ked.
Also i do have a Arasaka Type 99, the rounds are alil hard to find but i would take that for long range if not Mauser 98K, arounds are everywhere just about and they pack a HUGE punch in targets like the Arasaka.
Veichle? i dunno, probably anything i could get my friggin hands on, SUV, truck car doesn't matter!
The one thing that comes up to mind though is what are oyu wearing? i mean what kind of clothing? because of the chance of infection you would have to wear body armor but you cant be heavy so you can escape easily. I dont think shorts would be a good idea and i'm sure wearing a jack or something that would cover your flesh. I'd probably wear my dickies with a tee shirt with a trentch coat so if i have to hide it'll cover me. also, if you remember in those movies zombies could smell! yes thats right.. not only hear you but could f**king smell your ass, so carrying sent of other kinds could be use full.
