You are not the only person left alive, other people have weapons from the category that they chose, you can have edged and contact weapons, your surroundings are your current locale, but you can move if you wish, this is America after all, you can be a nomad or scavenger if you want (see above comment about America), your food supply could be your local Wally World or you can live off of the land, I'd hope you're on Earth, I know I am, you can live on whatever you want, land or water, you can walk upright if you want, I don't know about you, but I don't like crab walking.Too many unknowns to play along;
Am I the only person left alive?
Do other people have weapons and if so what type weapons do they have?
Do I have access to edged and contact weapons?
What are my surroundings?
Am I nomadic scavenger or a hunter/gatherer?
What is my food supply and where does it come from?
Am I on earth?
Do I live on land?
Do I walk upright?
What do these ink blots look like to you?
