The few words that came to mind for me were: Isolation, Survivor, Scavenger
My present idea is a wasteland idea where the player doesn’t really come across many other people, and enemies / creatures are countless. Its kind of survive in spite of everything and use whatever you can to achieve that. I guess imagine something similar to a cross between the Metro series and Fallout.
Still a work in progress, hoping to get a better idea as I continue the course.
