Friday the 13th: The Game is getting a new game mode soon and Gun Media has released a new teaser trailer for game mode called "Paranoia". While no additional details have been revealed, most people assume that in this game mode, one of the camp counselors themselves is going to be the one doing all the killings and thus no one will truly know who the killer is unless they reveal themselves.
We also did see glimpses of Part 8 Jason's mask in the trailer with blue chevrons, which I assume is a reference to Friday the 13th Part 5. Without spoilers, even though it's a 30 year old movie at this point, let's just say that this game mode will make perfect sense for that movie. The end of the trailer also has the hashtag "whoisfiVe", again which I assume is a reference to Part 5.
No release date but the game mode will be free of charge when it releases.
