CG Hub is a great site that allows you to browse some phenomenal artwork as well as getting access to concept art for games that may not be seen anywhere else.
Well, seeing as how PlayStation All-Stars Battle Royale is hot this week, I searched for art that was based on the game. I was lucky enough to come across these pictures which were created by someone working on the game. They say, on their page, that these were made as potential marketing tools, but were never used. Cool, right? The internet allows for people like myself to come across gems like these and then share them with you! Worship me.
