I know very little about P.N.03 as I have never played it, but I did find some good buttshot pics of the female star, Vanessa. For more info about the game, I refer to wikipedia
"P.N.03, short for Product Number Three, is a 2003 video game developed by Capcom for the Nintendo GameCube. P.N.03 is a third-person shooter featuring a dexterous, cybernetically-enhanced woman named Vanessa Z. Schneider who the player controls to destroy a series of robots. "
Here Vanessa gives us a better view of her butt cleavage.
