Interplay has released the second piece of concept art from Project V13. You can now view all the art in our gallery here. I do recommend that you sign up on the Interplay forums, though, as there are quite a few important people who frequent them (ie: Chris Taylor, daddy and lead designer of Fallout, and now lead systems designer on PV13).
In other news, I have some interested documentation related to a non-game matter which will take me a long time to read through. Once I have, I'll share my findings with you.
