It could be a PC2 fangame based on horror content, such as creepypastas, indie games, analog horrors, etc.

MY EXPECTED ROSTER

• Slenderman

• Jeff the Killer

• Smile Dog

• Eyeless Jack

• John (Minecraft Creepypasta)

• Springtrap

• 2011X

• EYX

• Faker

• The Boiled One (Doctor Nowhere)

• The Dog (Duck Season)

• Ink Demon

• Mimic (Vita Carnis)

THE CHARACTERS I COULD CROSS OUT OF THE GAME

• Alternates (Mandela Catalogue): Their attack method is about the psychological warfare to make the survivors commit s-word, not physical harm done; also controversies surrounding Alex Kister.

• Poppy Playtime cast (Huggy Wuggy, Mommy Longlegs, Catnap, etc.): I wouldn't include any from this game due to having bunch of content farm channels as well as having copyright restrictions and my dislike from this game's company for their workers mistreatment.

• ONAF cast (Flumpty, Grunkfuss, etc.): Jonochrome (the creator behind ONAF) is involved in controversies.

• The Man in the Suit: General dislike of the series.

• Any heavily-copyrighted character (Freddy Krueger, Jason Voorhees, Mario, etc.): I would want to avoid any lawsuits from the bigger studios.

• Any character that their creator is involved in controversies: I wouldn't like to be involved in stuff like these.
