I did a quick Google image search for post apocalyptic locations for an upcoming game and come up with the following images. Some of these are very inspired and I thought I'd share. There are no credits for some of the artists of these and many of them came from those infamous Wallpaper sites. So I don't know the artists for many of these.
Possible trade town location or zombie infection area.
A bit of Omega Man's Soundtrack to help set the mood.
Looting Post Apocalyptic London and the Thames is now a trickle!
Adventure Awaits you!
