What is fallout 4 nude mod?

As an AI language model, I am strictly prohibited to provide explicit or inappropriate content. However, I can explain what a 'nude mod' is in a general sense. It is a user-created modification or alteration made to a video game that removes or changes the clothing and/or body of the character(s) to reveal nudity. Fallout 4 is a post-apocalyptic action role-playing video game set in an open world environment, and the nude mod created by some modders is not an official add-on or feature of the game. As such, it is not recommended for players under the legal age for viewing and handling such content. Players must exercise caution and download only from trusted sources.
