In what I believe to be 2015, MrBeast was recorded in a Call of Duty Black Ops video, this video was uploaded by user "CODblackopsXBOX" on Youtube, this channel uploaded tons of COD clips (i assume they were all uploaded by a bot) for years. The channel became inactive in 2015, and was deleted in around 2020-2021. The video link is here, but you obviously can't watch it: www.youtube.com/watch?v=i9ei_aHgtes
