What would you do if the world ended and you were one of the few survivors left. You and the wild. I would just look for other survivors, look for a gun, and barricade myself in from "zombies"
depends if there ar zombies or not and how the world ended. If there were no zombies and human structures were intact I would skate alot and look for food and survivers in between
If the world actually "ended", the Earth would be obliterated. Though if civilization collapsed and humanity was nearly wiped out, I'd probably try to get back on my feet and adjust to the situation. Once I'd have sufficient supplies, resources, supplies and shelter I'd go looking for survivors.
The end of the world doesn't necesarrily mean zombies you know. There could be several different things that cause the end of the world (or become of it).
There could be a portal machine that opens a portal to hell, and hellish creatures and satan himself would wreak havoc among the world! -Ripped straight outta doom 3.
You could also have zombie outbreak (of all sorts, don't even get me started about how many different zombies there are, dude), which bring about the end of the world. But yeah, killing zombies is actually incredibly hard depending on the virus.
Nuclear holocaust could be the end of the world, where everything you know is completely screwed, and the world (except for a certain few parts) is un-breathable.
There's also the all famous machines rebelling against us a la "The Matrix". Causing people to be in constant hiding from something as seemingly harmless as a cell phone.
