Intrepid videographer HazardHeresy noticed that when leggy survivor Xian struggles to her feet in Dead Island, you can get a glimpse of her landing strip. No, really, she's going commando. Fast forward that video past the stupid-long preamble to 1:53 and you'll see what he's talking about—helpfully zoomed in close-up.
As grateful as I am for this particular bit of research I don't think this rises to the level of scandal, certainly not "Hot Coffee," which involved actual
sex-having fucking. This is an M-rated game. Know what else was M-rated? Grand Theft Auto: The Lost and Damned, and that featured full-frontal nudity. Male nudity, as in, actual wiener. So, no, even if the ESRB hall monitors missed this, it's not gonna get the game pulled.
