According to the ESRB, it’s been revealed that one of the characters from Resident Evil 6 has been accidentally leaked through the rating board. One of the game’s bosses has been described as the following;
One female boss character (a human-spider hybrid) is depicted nude—though without any discernible details (i.e., no nipples or genitalia); during one attack move, she briefly caresses her breasts while straddling on players’ character.
Unfortunately no screenshots were revealed at this time. You’ll just have to wait until the 2nd October release date.
