Influenced from GTA San Andreas, players modified GTA Vice City and included a fabricated Slenderman in the game that can be witnessed in the Haunted Mansion. The myth was first introduced in GTA Vice City by J* when he uploaded a video about Slenderman. In the video, he recorded an encounter with Slenderman in the Haunted Mansion, according to J*, the video wasn't modified. However, it was a blatant hoax and J* modified one of the members from the Shark gang into a Slenderman taking advantage of the members' tall height. Later on, several other modded videos were made by PS Knight on Youtube, three years later in 2015 when he included an extended arm Slenderman in the Vercetti Estate Basement. Despite these custom made skins, YouTube hoaxes and mods, Slenderman doesn't exist in the game.
