The world ended less than a decade ago and you are in Nebraska. It ended during the new years and all technology is from before the end or is basically the level of the Amish.

The major cities are occupied by aliens. The rest of the country is crazy splatterpunks, paranoid survivalists, regular people, bughunting irregulars, and NORAD.

Nebraska is part of flatland, a geographical region. The local resources are corn, corn, corn, and corn. Also wheat, potaotes, and whatever is grown during crop rotations. So beans and peas, but maybe using less water.

New houses are made of Sod.

"Money" is generally precious metals, ammo, rations and preserved food, soap, fuel, and materials.

You are an amorphous blob of random people in the southwest corner of the state.

Your objectives are either to kill as many splatterpunks or bugs as possible, to approach a high standard of living, to form thriving community, or replace the last semi-banditry militia that just got wiped out.

Or perhaps restore the Union. Or some mixture.
