Thanks to an anonymous poster on my last entry for giving me a link to this screenshot. Nice work, but both the logo (reading ´ARGHUSS´, as far as I can make out) and the copyright line (without a proper Retro Studios logo or a copyright sign) look very amateurish. My guess is it´s from DeviantArt. That would explain the quality of the image contrasting with the hastily added logo and the rest.
EDIT A number of people commenting on this story have pointed out that this could be a screenshot of ´Too Human´, a game being developed by Silicon Knights. It does look reasonably similar, but I´ll go out on a limb here and state that it´s not. I have checked a fair number of sites out there and that particular screenshot is nowhere. I have also searched DeviantArt for at least an hour. I would still say it´s fake. But where the screenshot comes from I don´t know.
