Duck and Cover managed to get their hands on some previously unreleased Project V13 (the Fallout MMO that Interplay can't name as such because of its legal battle with Bethesda) concept art. Unfortunately, DAC's admin King of Creation decided to add huge, lame watermarks in the middle of each pic.
Fortunately, KoC forgot that I also know the very same person he got the images from, and I just uploaded non-watermarked versions for your viewing pleasure.
- Update 2
The "Power Armor" concept art has now also been released with the title "Badass Armor" at Interplay's Project V13 concept art forum.
