So the what, the world basically just came to an end. What will you do, rob Walmart for food, live in the white house, play Blockland. Just because just about everyone has died doesn't necessarly mean that you have commit Self Delete, you can enjoy it.
1st: post the situation. What happened did Zombies kill everyone, or maybe aliens. Who is still living, your dog, your friends, your hot girlfriend, or maybe just yourself.
2nd: post what you will do. How will you live now, live on a boat, camp out at Walmart, find a cure, or just kill all the zombies with your grenade launcher and restart the population.
Also remember: There doesn't have to be zombies, lots of things could cause a situation like this.
Here's mine:
A new disease comes along. It kills almost everyone (only humans), but I accidenatally came across the cure. There's only enough for a handful of my friends, and a selection of girls. Since we are all resistant to the virus, it dies. Then we hotwire some cars steal all non-parsiable food from any store somewhat close. Then we go and live in a mansion. Restart the population. Then get more food, and supplies.
My imagination is rather weak today, idk why.
