After discovering the issues in "post-release monitoring and play-testing," the ESRB initiated a review of the game's original ratings process. The board cross-examined the tape Bethesda submitted with video taken from the final release of the game, and ultimately determined that the developer understated the detail and intensity of the blood and gore in the game. In reference to the nude skin, which is inaccessible during normal play and so couldn't have been included in the taped submission, the ESRB said publishers are required "to disclose locked-out content during the rating process if it is pertinent to a rating," and that Bethesda failed to do so.
